Hmm, perhaps you could try something like this:
:tmap <expr> <Esc>b SendToTerm("\<Esc>b")
func SendToTerm(what)
call term_sendkeys('', a:what)
return ''
endfunc
No idea if this works, haven't tried it.
That appears to work fine!
A follow-up on this: I have found that a drawback of your solution is
that, in an instance of Vim run inside a Vim terminal window, I need to
type Esc twice to return to Normal mode (I often happen to run Vim
inside Vim e.g., when I `git commit`).
What I am using now instead is this:
tnoremap <s-left> <esc>b
tnoremap <s-right> <esc>f
The first time I tried, I used ^[b and ^[f (with literal Esc), but that
did not work (^[b and ^[f on the rhs were translated into <s-left> and
<s-right> because of my settings). With <esc>, though, it works as
expected.
To recap, my configuration is as follows:
1. My terminal sends ^[b and ^[f when I type alt-left/right arrows.
2. In my vimrc, terminal keycodes ^[b and ^[f are tied to Vim
keycodes <s-left>/<s-right> using:
set <s-left>=^[b
set <s-right>=^[f
This makes alt-arrows work as shift-arrows in Insert and Command
mode, which means that I can jump between words with those key
combinations. A Vim terminal window, though, now sees \033[1;2D
and \033[1;2D when I type alt-arrows (because Shift-arrows are
mapped to those sequences by my terminal).
3. To fix that, I remap <s-left> and <s-right> in Terminal mode to send
the original sequence:
tnoremap <s-left> <esc>b
tnoremap <s-right> <esc>f
So, now I have alt-arrows work consistently in all modes, even in Vim
instances run inside a terminal window run inside a Vim instance run
inside etc... and Esc returns to Normal mode immediately under all
circumstances.
I don't know whether this strategy has any drawback (it seems fine so
far for me), and I may be missing something.
But if it is useful, you might want to update the terminal-special-key
section in the manual.
Life.
