I started to use Linux Mint. On the Terminal, I can use emacs -nw and emacs. I can't get the same key behavior about the following two configs. In particular, these settings work in emacs, but not in emacs -nw. How do I fix this issue?
(global-set-key (kbd "<C-tab>") 'other-window)
(define-key ess-mode-map (kbd "C-%") "%>%")
Terminals can't send <C-tab>.
The tab character in a terminal is TAB which is the same thing as C-i, and you obviously can't send C-C-i, so there's no such thing as C-TAB from a terminal's perspective.
That's not the only issue, though -- GUI environments have lots of key events that terminals don't send, so unless you're using a terminal emulator with special support for such modern things, there will be plenty of keys that you can't use.
