How to close initialization cell in Notebook? - wolfram-mathematica

In my Notebook I have a fairly large initialization cell. How to make it close-able? I mean how can I roll up this cell in one line with ability to unroll it back?

The classic solution is to put the initialization cell(s) into a Section (Alt+4) of their own, titled "Initialization." This Section goes either at the start or end of your notebook.
To hide the contents, you close the Section (double click its cell bracket at right of window).

I have found the solution. I should create a text cell before my initialization cell, for example here is a nice cell:
Cell[TextData[StyleBox["Initialization cell(s)",
FontFamily->"Courier New",
FontSize->14]], "Text",
CellFrame->True, ShowGroupOpener->True,
Background->GrayLevel[0.85]]
Then I should select this cell and the next (initialization) cell and then select from the context menu "Group Cells". Now I can roll up this group in one line corresponding to the first text cell by double-clicking its cell bracket at right of window. This is what I searched for. Thanks Andrew Moylan and Brett Champion.

Select the cell, then toggle Cell > Cell Properties > Open. The cell bracket will collapse to a few pixels high and be the only visible part of the cell. The same menu item will also make it visible again later.

How do I shift a set of lines one space to the right within a text editor?

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.

Enterprise Architect - simple UI Tab Control

Is it possible to change number of tabs and tabs name in simple UI Tab Control? How to do it? (user interface diagram)
I'm using EA 11.
No. Tab 1 | Tab 2 | Tab 3 is part of the element's image and you can't change them. There is a workaround which works visually, but won't help if you're looking to generate code out of your models.
Create a Text element (in the Common toolbox), and give it the name of your GUI's first tab.
Set a different default fill and text color for the Text element (Right-click and select Appearence - Default Appearance).
Pick the Fill and Border Color for the Text element that best matches the Tab Control's foreground, either in the diagram toolbar or the Text element's context menu.
Move and resize the Text element to cover Tab 1.
Repeat as necessary for the other tabs, using the appropriate color.
The Text elements are local to the diagram they're in and are not shown in the project browser (they are diagram objects but not proper model elements), but they move with the Tab Control so it works visually.
By making several copies of the Tab Control and varying which Text element has the foreground color, you can use this technique to show the different panes.
You can change number of tabs and selected tab this way (at least in EA 13):
Open Properties of the Tab Control;
In "General" select "Wireframing" tab. You'll see "Tabs" property with a value "Tab1";
Select this "Tabs" property and click on "Notes" menu. An editor appears;
In this editor you can change number of names of tabs;
Close editor and for "Tabs" property choose selected Tab;

Microsoft Word Highlighting Text White

For some reason, whenever I create a Text Box and start typing, the background text is highlighted white and I can't make it transparent. This picture should explain everything:
I want to remove the highlighting so the gradient in the background shows through. I used to do things like this a lot, but for some reason Word won't let me now. Any suggestions?
I am on Word 2011 Mac
Got some clues here and finally found a solution for MSWord for Mac version 16.9:
Select the text you want to fix
Select "Design" Tab
Click "Page Borders"
Click the "Shading" Tab
Select Apply to "Text"
[Fill] is showing "No Color". Open the selection and re-select "No Color"
Hit "OK"
Worked for me. It is obviously a bug in Word.
Right-click the text box that you want to make invisible.
If you want to change multiple text boxes, click the first text box or shape, and then press and hold SHIFT while you click the other text boxes.
On the shortcut menu, click Format Text Box.
On the Colors and Lines tab, in the Fill section, click the arrow next to Color, and then click No Color.
On the Colors and Lines tab, in the Line section, click the arrow next to Color, and then click No Color.
Click OK. Your textbox's background is now invisible...
It seems the actual text highlight is your problem, so try:
Go into Borders and Shading, apply it to text, and set it to clear. Had me confused because I've never had to do this before.
As seen here.
I also searched around and had trouble finding this.
In Word for Mac 2011
Highlight the text
Click tables in the ribbon
Find the shading icon (looks like a paint bucket)
Click the down arrow next to the bucket and select No Fill
Change the text format from anything apart from Normal text.(important)
Solution 1
Select the Text box and go to the "format" tab,
modify the outline and fill options
if this isn't enough
Solution 2
select the Text box and right click for options
select the last option "format shape"

View is Clipping its Content error

I'm using Xcode 4.6. In a window I keep getting this "view is clipping its content" error and when I click on it, the XIB editor highlights a label. What is this error trying to tell me and how to I fix it?
First, clicking on the text "View is clipping..." will select the control that has the issue. it happens when you resize a text field too small for the inner text field cell to fit in. enlarging the control makes warning disappear. you can also select the inner cell and go to size inspector to see if there are options to make it smaller to match your desired overall size.
You have a carriage return / newline at the end of the text in your label. That empty line is part of the "content" which is larger than the "view". Get rid of your extra newline and you'll take care of this.
It's telling you that your constraints hasn't been set up correctly. You can resolve the by clicking on the view in question, then clicking on the small icon at the bottom and choose: "Reset to suggested constraints"
Or you could click on the little small orange (or red) arrow in your Document Outline (the list to the left of your view that shows all views), then click on Resolve Issue

Cells & cellgroups in mma

This question and the comments and answers prompted this question. How do I effectively use Cells and CellGroups in mathematica? I've always only programmed systematically inside the input cells, entering the next line in a new cell after evaluating the previous. Looking around at the different options available, this seemed inefficient.
How do I use these more effectively? I tried organizing my code into sections using command-5 and into subsections, etc. But then when I try to get back to input cell with command-9, it doesn't evaluate it. I'm sure I'm doing something wrong, so help is appreciated.
Cell groups are just that, a way to group cells together. These groups can be easily selected, executed as one, and opened/closed (collapsed). By default these groups are indicated by a series of blue brackets to the right of the cells:
As seen above, output cells are automatically grouped with the input cell that created them. Also, the Section cell automatically groups the Text, Input, and Output cells below it. Finally the Title cell groups all cells below it, including the Section cell.
The different classes of cells that are available, such as Title, Section, etc., are determined by the active Stylesheet. The way they group is controlled by the option CellGroupingRules. This is a more advanced area, and details are probably better addressed in a different question.
Cell Grouping can be done either automatically, the default, or manually, or to a limited extent by a combination thereof. This is all handled by the menu commands in Cell > Grouping > ... or the keyboard shortcuts listed there.
If using Automatic Grouping, then styling a cell in a style that groups (as controlled by CellGroupingRules) will automatically group "lesser" cells and cell groups beneath it.
To style a cell, select the entire cell, not just the cell contents, by either:
clicking on the blue cell bracket (or the area where it would be if it is hidden)
clicking within the cell and using Alt+. until the entire cell is selected
clicking and dragging from above the cell, where the cursor is horizontal, to below the cell
Then, use menu Format > Style > ..., or the corresponding key combinations.
The same methods can be used to select cell groups, rather than individual cells.
To create a new cell of a particular style:
click outside of existing cells where the cursor is horizontal
this should create a horizontal rule as shown in earlier illustration
specify a style, again with Format > Style > ... or keyboard shortcuts
start typing (or paste) the contents of the new cell
To create a new Input cell, the default style, simply do step (1) and then type or paste the input.
It depends on your stylesheet. Input is not the nineth numbered style in every stylesheet. Also, you have to select the cell bracket to change a cell's style.
I use sections particularly to be able to use folding, i.e. the double clicking on the cell group bracket to hide the lower ranking cells. That makes for a clean document. It doesn't do anything with the Input cells (except for the context option).
