Can't bind "option+[KEY]" using MacOS.

[homedirectory]

I have the following commands in my .vrapperrc:

inoremap <M-i> <ESC>
nnoremap <M-i> a
inoremap <A-i> <ESC>
nnoremap <A-i> a

And the official documentation says: Similarly, Alt (meta) characters are mapped by using <A-x> or <M-x>.

However, this is what's happening upon pressing "option+I". Pressing any other key afterwards undoes it.

Can you try something for me? Hit qq to start recording into register q (the bottom-right of Eclipse will say recording: q). Then hit your option+[KEY] mapping, then hit escape a couple times to ensure you're back into command mode. Then hit q again to stop recording. After that, type :reg and hit enter to list the registers. There should be a register named "q which contains the keys you hit while recording the q register.

Can you tell me if it shows <A-i> or some other key mapping? I wonder if Eclipse is registering that option key as something else.

Also, it's possible Eclipse (or MacOS) already has something bound to the Alt+i key shortcut. If that's the case, Vrapper won't receive the keypress at all. I don't see anything online that says Alt+i is already bound in Mac or Eclipse but that could also be a factor.

1. Nothing else is boud to the Alt+i shortcut. Works in vim.
2. Below are the sequences of keys I pressed and the resulting contentes of "q register.

q, q, option+i, ESC, q

"q contains <ESC>

---

q, q, option+i, q

"q contains ˆ (not ^, i literally typed it using option+i)
