"C-S-something" doesn't seem to be a valid remap key

[kristian-clausal]

In the documentation there's an example of "C-S-esc" being used as an example, but the syntax "C-S-" does not work for letters, like "C-S-k" or "A-S-n". I couldn't get "C-S-esc" to work either, but that's not unexpected on a basic terminal (MATE terminal). "A-N" works, but some combinations like "A-I" and "A-O" don't, which is probably because they're caught somewhere else. Trying to use "A-O" does nothing on the first stroke and then "O" (new line before selected line).

In any case, the documentation for remapping could use some checking.

For character keys (i.e. not special keys like backspace or escape) we remove the shift modifier and shift the character: https://github.com/helix-editor/helix/blob/57e538d07b15c7ac33a0469f1ca05981704ee5af/helix-term/src/ui/editor.rs#L1495-L1503

So S- is only needed for non-character keys. The documentation lives here if you'd like to create a PR to add a note about this: https://github.com/helix-editor/helix/tree/master/book/src.

About the alt keys, yeah your terminal emulator or operating system is most likely eating those keypresses.

I am having a similar issue with the shift key on macOS

I am trying a config like

[keys.normal]
"C-N" = "extend_search_prev"
"C-n" = "extend_search_next"

[keys.insert]
"C-p" = "paste_after"
"C-P" = "paste_before"

In alacritty even when using capital version it always triggers the lower case binding. In macOS default terminal the capital case does not trigger anything. Is there a way to debug this further?

I've found similar issue, though without shift key. C-backspace = "delete_word_backward" doesn't do anything, and I've also tried in multiple shells and terminals (well, only two - bash and zsh, alacritty and xfce-terminal), thinking it's a me-problem.

On the other hand, C-del = "delete_word_forward" works fine, doesn't matter what command I use. Mode also does not matter - C-del works normal/insert, while C-backspace does not.

PS: Tmux or not, same issue.

That's unrelated: C-backspace has the same escape sequence as backspace by default. You'll need to use a terminal that supports the enhanced keyboard protocol https://github.com/helix-editor/helix/wiki/Terminal-Support#enhanced-keyboard-protocol

I'm encountering a similar problem as well trying to do the following:

[keys.insert]
A-ret = ["open_below"]
A-S-ret = ["open_above"]

Alt-Enter keybind seems to work for me but not the Alt-Shift-Enter one \ \ I'm using wezterm on macOS; it had no trouble receiving the chorded key event:
