Description Tim Siegel 2024-07-08 16:12:28 UTC

SUMMARY

Typing <C-[> (^[, Ctrl-[, Control-Left Bracket) should behave as Escape in vi mode. In particular, it should enter Normal mode when in Insert mode. Other instances are less crucial, but should still behave as Escape for consistency.

STEPS TO REPRODUCE
1. Open Kate. Set Default Input Mode to VI Input Mode.
2. Type "ifoo" to enter insert mode and add "foo" to the buffer.
3. Type <Ctrl-[>, notice that nothing happens. Nothing is added to the buffer, and the editor remains in "VI: INSERT MODE".
4. Type <Escape>, notice that the editor switches to "VI: NORMAL MODE".

OBSERVED RESULT

Ctrl-[ does nothing

EXPECTED RESULT

Ctrl-[ behaves as Escape

ADDITIONAL INFORMATION

This behavior is standard in the terminal since at least the late '80s (I don't know the full history). I searched for a similar bug report or discussion, but could not find any prior mentions of this problem.

Additionally, I could not figure out how to add a key mapping in Kate to accomplish this as a workaround.

Comment 1 Audrey Meyer 2024-07-19 22:02:14 UTC

It seems that this is already a feature but it's being superseded by a global shortcut.

WORKAROUND:
1. In System Settings, go to Keyboard->Shortcuts->Navigation.
2. Uncheck "Ctrl+[" under "Activate Previous Tab".
3. Restart Kate, Ctrl+[ should now work like escape in Vi input mode.

Comment 2 Waqar Ahmed 2024-10-16 19:06:21 UTC

Seems like Next tab/Prev Tab take up two shortcuts each!!! Thats a bit alarming for Kate as we are already running low on shortcuts and there's stuff overusing it :/

Anyways, that's a standard kde shortcut, unlikely that will change. Perhaps we should remove the fallback shortcut in Kate

Perhaps we should do that.

Comment 4 Waqar Ahmed 2024-10-22 04:08:08 UTC

Turns out its not 2 shortcuts, its at least 3:

QList(QKeySequence("Alt+Right"), 
QKeySequence("Forward")) 
QList(QKeySequence("Ctrl+PgDown"), 
QKeySequence("Ctrl+]"))
