If I want to delete few lines of text in most of text editors, not touching some words on the bottom line and the whole upper line, I put cursor on the bottom row leaving all unnecessary words to the left of the cursor. Then I select few lines vertically by holding Shift + ↑. I stop on upper row and get some selection: part below + right part of the upper row:
In this example I want to get rid of if word and an empty space between the function header and the code, not touching the function header (even hough let will stick to the opening bracket {).
Normally (not in Xcode) I would still hold Shift and will press cmd + ➝ to deselect the right (selected) part or the top row.
Result will be like this:
I can simply press Delete and job is done.
However, in Xcode such shortcut usage makes bottom row fully selected (till the right) and not changes upper row selection:
Same thing happens if you select from top to bottom and you need to remove extra selection from the bottom line.
I tried to rebind shortcuts in Preferences but didn't find a solution.
This example is very particular and maybe not the best, however I face such selection problems only in Xcode and have to use mouse which is not handy.
This is a rather old question, but what you want is fairly simple to achieve. If your cursor is between the if and the let, you would only need to press option-shift-left arrow twice. The first time, it would select the if and the leading tabs, and the second would select the empty line.
How do I shift a set of lines one space to the right within a text editor?
If I wanted to shift a set of lines several spaces to the right, I would perform:
selected text + Tab
However, I just want to shift the text one space to the right without tabbing.
Any suggestions?
Hold down the alt key, left-click and hold the mouse button down on the first line where you wish to insert your space. Then, while still holding down the left mouse button, drag the mouse vertically to extend this edit point to all the lines you want to move. Dragging it horizontally will create a box selection, which you want to avoid, as the selected text will end up being replaced, rather than a space be added.
Also, you cannot select individual, disjoint lines to move. You can only use alt-drag over a contiguous block of lines.
Once you have your multiline edit point created, hit the spacebar once.
Tada.
Here's a blog post by Scott Guthrie with more details and a vidya demo
If you don't want to use the mouse, you can use shift+alt+(up, down, left, or right) to create a box selection, or a multiline edit point.
My question today is, when selecting multiple lines of code and not completely selecting the full line for all the lines selected, how can I (or is there any keyboard shortcut for) block select all the lines that I have already selected, so that I have not just some lines fully selected and some not fully selected, but all the lines are fully selected from the home of the top line selected, to the end of the last line selected?
Note: The bold text in the segment above is what I am mainly trying to ask.
Thanks to anybody that is able to provide me with any helpful information!
From your question it looks like you want to select a block and not the complete line.
Hold the alt key and use the mouse to select your block.
You can use Alt + Shift + Arrow keys..
Its called Box Selection and was introduced in VS2010.

Textbox textwrap property is set to wrap.
My scenario is enter the text in textbox from SIP. When cursor reaches almost at the end of line may be 3 or 4 char left for line change just enter space so that it should came to next line. But after pressing space 4 or 5 time or more the cursor will not come to next line moreover it will not shown . It will come to next line when i enter some char.
I think it should came to next line because user may want to enter some space. is this can be fixed.
The other property you need to set on the TextBox is AcceptsReturn to true.
Edit: This question had been tagged "Tolstoy" in appreciation of the quality and length of my writing:) Just reading the first and the last paragraph should be enough:) If you tend to select and move code with the mouse, the stuff in middle could be interesting to you.
This question is about how you use text editors in general. I’m looking for the best way to delete a plurality of lines of code (no intent to patent it:) This extends to transposing lines, i.e. deleting and adding them somewhere else. Most importantly, I don’t want to be creating any blank lines that I have to delete separately. Sort of like Visual Studio's SHIFT+DELETE feature, but working for multiple lines at once.
Say you want to delete line 3 from following code (tabs and newlines visualized as well). The naïve way would be to select the text between angle brackets:
if (true) {\n
\t int i = 1;\n
\t <i *= 2;>\n
\t i += 3;\n
}\n
Then hit backspace. This creates a blank line. Hit backspace twice more to delete \t and \n.
You end up with:
if (true) {\n
\t int i = 1;\n
\t i += 3;\n
}\n
When you try to select a whole line, Visual Studio doesn't let you select the trailing newline character. For example, placing the cursor on a line and hitting SHIFT+END will not select the newline at the end. Neither will you select the newline if you use your mouse, i.e. clicking in the middle of a line and dragging the cursor all the way to the right. You only select the trailing newline characters if you make a selection that spans at least two lines. Most editors I use do it this way; Microsoft WordPad and Word are counter-examples (and I frequently get newlines wrong when deleting text there; at least Word has a way to display end-of-line and end-of-paragraph characters explicitly).
When using Visual Studio and other editors in general, here’s the solution that currently works best for me:
Using the mouse, I select the characters that I put between angle brackets:
if (true) {\n
\t int i = 1;<\n
\t i *= 2;>\n
\t i += 3;\n
}\n
Hitting backspace now, you delete the line in one go without having to delete any other characters. This works for several contiguous lines at once. Additionally, it can be used for transposing lines. You could drag the selection between the angle brackets to the point marked with a caret:
if (true) {\n
\t int i = 1;<\n
\t i *= 2;>\n
\t i += 3;^\n
}\n
This leaves you with:
if (true) {\n
\t int i = 1;\n
\t i += 3;<\n
\t i *= 2;>\n
}\n
where lines 3 and 4 have switched place.
There are variations on this theme. When you want to delete line 3, you could also select the following characters:
if (true) {\n
\t int i = 1;\n
<\t i *= 2;\n
>\t i += 3;\n
}\n
In fact, this is what Visual Studio does if you tell it to select a complete line. You do this by clicking in the margin between your code and the column where the red circles go which indicate breakpoints. The mouse pointer is mirrored in that area to distinguish it a little better, but I think it's too narrow and physically too far removed from the code I want to select.
Maybe this method is useful to other people as well, even if it only serves to make them aware of how newlines are handled when selecting/deleting text:) It works nicely for most non-specialized text editors. However, given the vast amount of features and plugins for Visual Studio (which I use most), I'm sure there is better way to use it to delete and move lines of code. Getting the indentation right automatically when moving code between different blocks would be nice (i.e. without hitting "Format Document/Selection"). I'm looking forward to suggestions; no rants on micro-optimization, please:)
Summary of Answers
With respect to Visual Studio: Navigating well with the cursor keys.
The solution that would best suit my style of going over and editing code is the Eclipse way:
You can select several consecutive lines of code, where the first and the last selected line may be selected only partially. Pressing ALT+{up,down} moves the complete lines (not just the selection) up and down, fixing indentation as you go. Hitting CTRL+D deletes the lines completely (not just the selection) without leaving any unwanted blank lines. I would love to see this in Visual Studio!
In Emacs:
kill-line C-k
transpose-lines C-x C-t
C-a C-k C-k -- kill whole line including newline (or kill-whole-line by C-S-backspace).
C-u <number> C-k -- kill <number> of lines (including newlines).
C-y -- yank back the most recently killed text (aka paste)
In VIM:
Delete the whole line including the newline: dd
Transpose lines: dd p
You can always prefix any command with a number to repeat it, so to delete 10 lines do:
10 dd
You can also specify a range of lines to delete. For instance, to delete lines 10-15:
:10,15d
Or you can move the lines, for instance move lines 10-15 below line 20:
:10,15m20
Or you can copy the lines:
:10,15t20
What I do is, starting with the cursor at the start of the line (in some editors you have to press home twice to do this), hold shift and press down until all lines that I want to delete are selected. Then I press delete.
In Eclipse you can ALT-↓ or ALT-↑ to move a line. I find this incredibly useful, as well as ALT-SHIFT-{↓, ↑} to copy a line. In addition, it doesn't wreck your clipboard. It even corrects indentation as the line is moving!
Adding to the existing vim answer, you can use d along with any cursor movement command to delete from the cursor's current position to the new position. For example, to delete...
...to end-of-paragraph (usually meaning "to the next blank line"): d}
...the line containing the cursor and the next 5 lines: d5j
...a set of parentheses, braces, etc. and its contents: d% (with the cursor on the opening or closing paren/brace/etc.)
...to the third appearance of the word "foo": d3/foo
It's quite flexible.
Learn to use your cursor keys.
For moving lines I do the following:
Use ↑/↓to move to the line you want to copy.
Hit Home if not there already, and again if it places the cursor after whitespace.
Then press Shift+↓ to select the line (or lines) you want to move
Ctrl+X to cut the line.
Move Up/Down to the line you want to insert
Ctrl+V
This should work in pretty much any text editor on Windows.
When deleting lines I still tend to use Ctrl+X (although I guess I also use backspace) as the above is so ingrained in how I edit, and it's also more forgiving.
(Although I find them disorienting on the occasions I use Macs, I think Apple might have been on to something with the way they've set up the Home/End, skip word shortcuts on Macs)
Ctrl+Shift+L removes line without copying it to the buffer.
in Eclipse i use CTRL+ D to delete a single line (or a couple)
for many lines i'll select them with the mouse or with SHIFT + ARROW then press the DEL key.
In addition to the above, use Resharper for Visual Studio to do what you want. Best VS plugin you will find ever. It provides a bunch of different commands that help with moving/deleting/copying code here there and everywhere. Not to mention refactor/generate/etc code.
Ctrl-Shift-Alt ↑or ↓ will move a method up or down, line up or down, etc.
Shift-Del - deletes the current line, but puts it in the clipboard (unless you modify your settings to not do this - I'm trying to recall if this is a VS standard shortcut, not just Resharper - been too long).
Ctrl-C, Ctrl-X without selecting copies/cuts the current line.
And on and on...
See http://www.jetbrains.com/resharper/docs/ReSharper40DefaultKeymap2.pdf for a full list.
Using the Brief keyboard mapping this is done using the Alt+L to mark the line and the - key on the numeric keypad (or Alt+D) to cut the line to clipboard. The cut will remove the line entirely, including the newline character.
Hitting the Ins key on the numeric keypad would put the line back into the document including the newline character.
IMHO Brief is a really well designed keyboard mapping.
PS: I think MSVC has an option to emulate the Brief keyboard mapping.
In Emacs, in addition to C-k (and C-k with a numeric prefix arg, to kill N lines), you can just use the mouse:
To kill one line: triple-click it, then right-click twice
To kill multiple lines: triple-click the first line, then right-click on the last line ("first" line can be after the "last" line -- "first" here means first one you click)
