There is the known problem in using shortcuts like Ctrl+/ or any other shortcut with []{}-character in German layout. Normally it's fine to change the most usable shortcut i.e. Ctrl+/ to Ctrl+- for Comment with Line Comment-Shortcut.
The problem now is, that if I'm using both layouts - I want this shortcut to be always on the same place.
US layout:
German layout:
Now if I'm using US layout I have to use following keys:
So the question is - is there any way to make shortcuts (keymap) depend on the chosen layout?
Since I'm not getting any answer here - I've found small workaround. That's actually not directly an answer to the question, but it solves the problem for users with German layout.
Since I don't use Ctrl + - in English layout (collapse code block), I've defined both Ctrl + - and Ctrl + / for commenting line with line comment. Now I can comment line with pressing red buttons from picture above in both English and German layouts.

How can I block comment a selected text in an IPython Notebook with a German keyboard layout? Ctrl-/ does not work, which on a German keyboard actually is Ctrl-Shift-7.
I found this great workaround for international keyboard layouts from Dataman in How do I comment out multiple lines in Jupyter Ipython notebook?
Press the Alt button and keep holding it. The cursor should change
its shape into a big plus sign. The next step is, using your mouse, to
point to the beginning of the first line you want to comment and while
holding the Alt button pull down your mouse until the last line you
want to comment. Finally, you can release the Alt button and then
use the # character to comment.
I used it with nbextensions.
Install it. See docs here
Then, in your nbconfig.
Just configure it with your personal preference. I am using german keyboard and used this implementation successfully for months.
You can define custom keyboard shortcuts in custom.js. For Jupyter this file is located in .jupyter/custom/. On a German keyboard layout I use Ctrl + , as a shortcut to comment by adding this to custom.js:
define([
'base/js/namespace',
'base/js/events'
],
function(IPython, events) {
events.on("app_initialized.NotebookApp",
function () {
IPython.Cell.options_default.cm_config.extraKeys = {"Ctrl-," : "toggleComment"};
}
);
}
);
Well after trying every combination with ctrl, voilà, ctrl-# does the job.
On a Nordic keybord (and I think this goes for German as well) simply hit Ctrl+Shift+7 (=Ctrl+/)
I am working on several documents where I have to type [ ] { and the like (which is much easier with with an american keyboard layout (and to which I am used much more)) but where I also have to type Umlauts such as ä, ö and ü.
Usually, I go be setting up the (what I believe to be a standard) Windows Shortcut Alt+Shift to switch between these layouts.
This is unpractical, because at times I am not sure if I am already in the german layout when I need the german layout (and vice versa).
So, is there a better way to change the keyboard layout in Vim on *OS-level"?
I guess it could be solved with changed :map and :imap but I'd rather not use these for such porposes unless really forced to.
I don't think there is such an option - even though vim can even make pancake for you!
It'd be highly unlikely for any program to allow changing the keyboard layout of regular keys since basically any OS already supports it.

Do you have the language bar enabled? It should have an icon that represents your current settings.
Microsoft Knowledgebase article: HOW TO: Use the Language Bar in Windows XP
If the only thing that you need is to add umlauts easily, Vim has built-in support for adding these characters:
Method 1. In insert mode type: CTRL-K a: to give ä.
Method 2. If you use :set digraph you can enter a<BS>: to give the same result.
These methods will work with any character that needs umlauts, just use CTRL+K o: or CTRL+K u: respectively.

Maybe you could be interested in some Dvorak layouts (mine is bépo, maybe it could suit you?)
What is the keyboard shortcut navigate back to the last cursor position in Visual Studio?
It Will not work for red color (-) key. For me it only works for blue color combination.
According to Visual C# 2008 Keybinding Reference Poster it is Ctrl + -. The name of the specific keybinding is View.NavigateBackward.
PS: While researching I also found that Ctrl + . is the same as Shift + Alt + F10. Nice!
ctrl + - (dash) navigates backward.
ctrl + shift + - (dash) navigates forward.
These settings can be found under Environment -> Keyboard:
For Changing the setting in Visual Studio 2019:
Search for view.navigate
CHOOSE "Text Editor" from the "Use new shortcut in:" drop down menu
Select your shortcut
Global doesn't catch for this.
For new VS Code(1.28.2)
Back: Ctrl+Alt+- (dash)
Forward: Ctrl+Shift+- (dash)
The most generic answers is: there is no working default and you need to define your own keyboard shortcuts for View.NavigateBackward and View.NavigateForward.
Why? For most keyboards, the default shortcut is a broken, unusuable combination because VS badly handles the shift and altGr modifiers. MS did not pay attention to portability and internationalisation so much when they redeveloped VS after version 6, and this is still true today. This bug has been there for way more than a decade, nearly two decades. At this rate, it will never be fixed. And yes, I have filled a bug report, and I'm certainly not the only one.
However, their "VSCode" product line does have better keyboard handling as it doesn't depend on the shift or altGr modifiers to identify the key. For example, when you are in text writing mode and press the key that has the dash symbol, without using shift nor altGr, let's say it writes something else, like number 6. To VSCode when it comes to shortcut handling, that's still the dash key for its purpose. As long as a key has the symbol written on it, whether this is painted as the 1st, 2nd or 3rd level doesn't matter, it just that key.
Of course, it's never a good thing to make the default shortcuts use non-alphanumeric symbols, that's always confusing, whether it works or not. The good mature text editors have known that for a long time and should be taken as examples of things done right. In some ways, VS learned a few good things from emacs with shortcuts that are a sequence of two letters, but ultimately screwed up on other parts with the choice of non-alphanumeric bindings, combined with a broken low-level keyboard handling.
This works for me in Visual Code
Navigate backward Alt+←
Navigate forward Alt+→
I imagine that there are different combination, just looking for an affirmation. Or, are we developers really that english-centric?
If I were in Japan, using a word processor on some computer, would Ctrl + S save?
Are there keyboards where Ctrl + S doesn't even exist (non-english keyboards)? Most of what I've seen usually has latin + [insert language here] characters, usually overridden on the normal qwerty keyboard.
It depends.
If the application's UI is in English, most people will expect CTRL + S to save.
If you're writing an application that is going to be translatable, you probably want also the shortcuts to be translatable. Shortcut standard varies between languages and countries. Leave this to the translator.
Yes, Ctrl- and Alt- are usually passed on verbatim and not subject to IME processing—assuming one is using an IME; I don't know about IME-less JP input methods. But in the basic case where an IME is used, Ctrl-S remains Ctrl-S, it does not become Ctrl-す or something.
Furthermore, menu entries often have a Latin accelerator defined - cf. http://www.marsei.net/tec/tecladoEspWindows.jpeg :
addmenuentry(m, "ファイル(&F)");
Just tried on my Mac by setting Spanish as my default language. None of the programs I opened used different shortcuts in Spanish than English, although the menu text was all translated. TextEdit was the main program I used to test.
I also tried setting my keyboard to the Dvorak layout (very different layout, still meant for English), Spanish layout (still QWERTY), and French (a & q, z & w, m & , & ; swapped). Even though the French keyboard had the q in a different place, the shortcut was still CMD-Q.
So, it seems the convention on Mac OS X is to have the shortcuts always use the same letters.
However, according to this link, in Spain CTRL-G(uardar) is normally the shortcut for saving: http://www.ixda.org/node/18527.
Here's an argument for basing the shortcuts on the position of the key on the keyboard, but I'd be surprised if anyone actually does that. http://blog.i18n.ro/are-we-supposed-to-localize-keyboard-shortcuts/
In Visual Studio, CTRL + S saves the document. In MS Office it's the same if it's in English, otherwise if it's in Italian, CTRL + S underlines the text, while SHIFT + something saves the document. I have no idea why they did this, but it might also apply to other applications and languages.
It depends on what you want to write. if you want to write a program and want to publish it everywhere, you should decide if you want it to write in only one language or in lots of languages. If you only want to write it in English, every one that wants to use it should change his/her system language to English or at least should support English. In that way Ctrl + S will do what you want.
I'm using Notepad++ as an editor to write programs in Python. It might sound daft but I looked around in the editor and could not find any means (not the manual way but something like in Emacs) to do a block comment in my code.
Since so many language settings are supported in Notepad++, I'm curious to find a way to block comment code.
CTRL+Q Block comment/uncomment.
See Keyboard And Mouse Shortcuts - Notepad++ Wiki.
Try the following shortcut:
Ctrl+K.
This link was exactly what I was searching for .
Let me summarize the answers for others' benefit (for python and notepad++)
1) Ctrl+K on multiple lines (i.e. selected region) allows you to block comment.
Also note that pressing the combination multiple times allows you to add multiple "#"s (sometimes I use that while testing to differentiate from other comments)
2) Ctrl+Shift+K (on the commented region) allows you to perform block uncomment
3) Ctrl+Shift+K on an uncommented selected region does not comment it
4) Ctrl+Q allows you to block comment/uncomment in a toggled mode (meaning, you cannot add multiple '#'s like in 1) )
Hope this helps another wandering soul.
Question - how would you develop a hack of keyboard combinations to comment/uncomment if there were no shortcuts? Just curious. I've no clue hence asking.
Yes in Notepad++ you can do that!
Some hotkeys regarding comments:
Ctrl+Q Toggle block comment
Ctrl+K Block comment
Ctrl+Shift+K Block uncomment
Ctrl+Shift+Q Stream comment
Source: shortcutworld.com from the Comment / uncomment section.
On the link you will find many other useful shortcuts too.
for .sql files Ctrl+K or Ctrl+Q does not work.
to insert comments in .sql files in Notepad++ try Ctrl+Shift+Q
(there is no shortcut to uncomment the code block though. I have tried that on v5.8.2 )
Use shortcut: Ctrl+Q.
You can customize in Settings
In your n++ editor, you can go to
Setting > Shortcut mapper
and find all shortcut information as well as you can edit them :)
Two ways for block commenting:
Ctrl+Shift+Q
or
Select the block
Alt + Right click
Choose block comment.
Without having selected a language type for your file there are no styles defined. Comment and block comment are language specific style preferences. If that's a PITA...
To select for multi-line editing you can use
shift + alt + down arrow
To add a comment under any code on NOTEPAD++ first we have to save and define the programming or scripting file type. Like, save the file as xml, html etc. Once the file is saved in proper format you will be able to add a comment directly using the shortcut ctrl+Q
Just select the desired line and click on Ctrl + Q
Ps: I am using Notepad++
