Thank you. My {lhs} is <F4> or <F5> which are single keys.
From your reply, I guess I should not add space characters in the command line.

I noticed my vim does not provide `:help CTRL-\_CTRL-G` in Fedora.
And seems vim-minimal package does not provide the full supports of vimrc.

After I installed vim-enhanced package, my vim can work with $HOME/.vimrc of the following content:

nmap <silent> <F4> :!ibus engine anthy<CR>a
imap <silent> <F5> <Esc>:!ibus engine xkb:us::eng<CR><CR

However feedkeys() still does not work.

imap <F5> <C-\><C-G>:call feedkeys("\<C-Space>")<CR>

When I press F5 key in the insert mode, I'd change the mode to the normal mode and send Ctrl-space key to xterm or gnome-terminal but not vim.
But the actual result is, <C-/><C-G> or <Esc> works but feedkeys() does not forward Ctrl-space to my input method.

Do you have any ideas?
