Ctrl-Backspace in gnome-terminal moves cursor left instead of deleting word #272

Closed mgedmin closed 7 years ago

mgedmin commented 7 years ago

Steps to reproduce

Hit <Leader>t to trigger command-t
Type some text
Hit Ctrl-Backspace

What I expect

the last path segment gets deleted
or, at the very least (assuming the terminal can't distinguish Backspace from Ctrl-Backspace) the last character is erased

What actually happens

the cursor moves left

Additional details

<C-V> <C-Backspace> in insert mode shows that gnome-terminal sends a ^H on Ctrl-Backspace. The regular backspace sends a ^?. Vim's &t_kb is ^?.

Thanks for the report. I am not sure how to work around this, short of replacing the default binding of C-h (which moves the cursor left) by setting g:CommandTCursorLeftMap (removing C-h) and g:CommandTClearPrevWordMap (adding C-h).

mgedmin commented 7 years ago

I'm curious: why is C-h bound to moving left by default? I would understand it being mapped to backspace (since I think some terminals still emit ^H for backspace), but I don't think I've ever seen it bound to moving left.

wincent commented 7 years ago

C-h, C-j, C-k and C-l and mapped to movement in directions corresponding to Vim's own h/j/k/l keys.

Let's close this as invalid then. I'm happy enough that I can tweak this with settings for my own convenience.
