micro: Key-press sequences broken under tmux
Description of the problem or steps to reproduce
Go to “raw” mode to show key presses. Press a key combo, like shift + left arrow. Directly from Konsole you see this interpretted as a single key press:
EventKey: “\x1b[1;2D”
However, under tmux you see the escape sequence as several separate key presses:
EventKey: “\x1b[”
EventKey: “1”
EventKey: “;”
EventKey: “2”
EventKey: “D”

- Add 'xterm' option Ref #1489 — committed to zyedidia/micro by zyedidia 4 years ago
This is solved now with the newest version of tcell. Micro now accepts
TERM=tmux-256color.I’ve added the
xtermoption, which will cause micro to think the$TERMisxterm-256colorregardless of what it actually is. It’s not a great solution, but it should resolve your problem without requiring you to change theTERMvariable.This appears to be caused by tmux declaring
TERM=screen. I’m not certain, but it seems likely that thescreenterminfo doesn’t declare the escape sequences for modified arrow keys, though tmux sends them anyway. I’m not sure if there’s a good fix for this (maybe just recognize those escape sequences regardless of the terminfo?) but one thing is you can declareTERM=xtermorTERM=xterm-256colorand as it seems like the escape sequences that tmux is sending are more aligned with the xterm terminfo.
