I can't write ^ or ~ in the command window. Is there a remedy for this?

I have no conflicting keyboard shortcuts. I have been able to input these characters in previous releases.

[TED MOSBY]

can you provide the full command you are trying to run?

[Gustav]

It's simply trying to input Alt + ^ or Shift + ^. I'm using a swedish keyboard layout.

Copy/past with your mouse?

@Gustav are you able to use same command anywhere else like a simple word doc?

[Rik]

On very old releases I need to type special characters ('"~) twice before they show up. Perhaps you can try that (even if it shouldn't be necessary in the first place).

[Gustav]

I can write ^ and ~ anywhere else, but not in matlab. Of course I can copy and paste, but I'm wondering if there is a more convenient solution.

[Bruno Luong]

Can you type those charaters on the editor or only it does not work in command window?

I don't know the technology behind keyboard input in window command, it looks like abnormal glitch to me, and you should report and get assistance from the official people.

@Gustav i am able press shift + 6 to get the ^ character, which MATLAB version are you using

Hi @Gustav

Your Swedish keyboard have this kind of layout?

[Gustav]

@Sam Chak Yes!

Those are dead keys. You can find discussions on them:

Hi @Gustav

Try remapping certain keys in your swedish keyboard.

• Microsoft Keyboard Layout Creator (MSKLC) Version 1.4
• Colemak layout

Thanks for the support! The solution I found was the following (working on Ubuntu 22.04.4 LTS).

1. In terminal: xmodmap -pke > ~/.Xmodmap

2. In .Xmodmap, change

keycode 35 = dead_diaeresis dead_circumflex dead_diaeresis dead_circumflex dead_tilde dead_caron dead_tilde

to

keycode 35 = diaeresis asciicircum diaeresis asciicircum asciitilde caron asciitilde

3. In terminal: xmodmap ~/.Xmodmap

Hi Gustav,

In addition to your solution, here are some general steps that others experiencing the same problem can try:

Use ASCII Codes:

• As a workaround, you can use ASCII codes to insert these characters. For example, in MATLAB, you can use:

char(94) % For '^'

char(126) % For '~'

Copy and Paste:

• Copy the ^ and ~ characters from another source (like a text editor) and paste them into the MATLAB command window.

Check MATLAB Preferences:

• Go to Preferences in MATLAB and check if there are any settings in the keyboard section that might be interfering with your keyboard input.

Check for Software Conflicts:

• Some third-party software or utilities (such as keyboard managers or custom drivers) might interfere with keyboard input. Try disabling them temporarily to see if it resolves the issue.

Reboot the System:

• Sometimes a simple reboot can resolve temporary glitches with keyboard inputs.

Hope this helps!
