Ctrl-Slash "/" does not work

[ingwiz]

Is there a way to make this keyboard shortcut (Ctrl-/) work in WSL? In Bash, this is an undo operation. I have tried Ubuntu 20.04 WSL and Oracle Linux 9.3 WSL. In the Windows Terminal application, this works as it should.

Hi! Here's a step-by-step guide to help resolve the issue with the Ctrl-/ shortcut not working in Fluent Terminal with WSL:

---

1. Check Fluent Terminal Keybindings

• Open Fluent Terminal settings.
• Navigate to the Keybindings section.
• Verify if Ctrl-/ is assigned to any other action. If so, either remove it or reassign it to a different shortcut.
• Save the settings and test if the issue is resolved.

---

2. Map Ctrl-/ in Bash

If Fluent Terminal passes Ctrl-/ to WSL but Bash doesn’t recognize it, you can configure it manually:

1. Open your WSL terminal.
2. Edit the ~/.inputrc file using a text editor, such as nano:

   nano ~/.inputrc

3. Add the following line to map Ctrl-/ to the "undo" operation:

   "\C-/": undo
   

4. Save the file (Ctrl+O > Enter) and close the editor (Ctrl+X).
5. Restart Bash to apply the changes:

   exec bash

3. Verify Keyboard Handling in Fluent Terminal

Some terminal emulators block or interpret key inputs before they reach the shell. In Fluent Terminal:

• Open the Settings menu.
• Look for an option like Pass all keys to terminal or Send raw input to shell (if available) and enable it.
• Save the settings and test again.

4. Test in Windows Terminal

If Ctrl-/ works in Windows Terminal, the issue might be specific to Fluent Terminal. In that case:

• Use Windows Terminal as a temporary alternative if this functionality is critical.
• Report your environment details (Fluent Terminal version, WSL distribution, etc.) here for further investigation.

5. Use an Alternative Shortcut

If fixing Ctrl-/ isn’t possible, you can assign a different shortcut for the "undo" operation in Bash. For example, in ~/.inputrc:

"\C-z": undo

Replace \C-z with any other key combination you prefer.

I hope this helps! Let me know if any of these steps work for you or if additional debugging is needed. 😊

@CryptGodSon Thank you for the guide.

1. There is no Ctrl-/ combination in the Key Bindings section.

2. Mapping key combination. I tried several combinations, but only \C-_ works, and it works in Windows Terminal and cmd.exe/ssh.exe, but not in Fluent Terminal.

3. I did not find any options Pass all keys to terminal or Send raw input to shell or something like that in Fluent Terminal Settings.

4. Windows Terminal. Ctrl-/ works. After command

   echo '"\C-_": undo' > ~/.inputrc ; exec bash

   the Ctrl-_ keys also work in Windows Terminal and cmd.exe/ssh.exe, but not in Fluent Terminal.

5. The key combination Ctrl-x Ctrl-u works in Fluent Terminal, I found out it here: https://tiswww.case.edu/php/chet/readline/rluserman.html#index-undo-_0028C_002d_005f-or-C_002dx-C_002du_0029
