vimrplugin_assign_map doesn’t work in terminal about vim-r-plugin HOT 4 CLOSED

The inability to map something like <M--> is not a Vim-R-plugin bug. It's a Vim/Terminal limitation, but I've just found the solution: http://vim.wikia.com/wiki/Get_Alt_key_to_work_in_terminal

If you want to press Alt+- to get _, then put in your vimrc:

set <M-->=�^[-
let vimrplugin_assign_map = "<M-->"

where ^[ is obtained by typing Ctrl+V Ctrl+[ in Insert mode. I'll add this information to the documentation.

Pity – that doesn’t seem to work in my terminal (iTerm2 on OS X, nor locally nor via SSH on Linux) since Mac uses the Alt key for something else. This is a known problem but the solutions from that thread unfortunately don’t work, not even in conjunction with set macmeta. I’m probably doing something wrong but this is certainly not trivial.

However, unrelated to the alt-key issue, the following also doesn’t work:

let vimrplugin_assign_map = "<C-->"

It seems that Ctrl can only be mapped to be followed by an alphabetic letter. Here, Ctrl-j does nothing useful and, thus, could be mapped to produce " <- ". It's not a mnemonic combination, though.

Ah. That works. Thanks a lot.
