How can I remap these keys so they work as Meta?
I'm trying to use Meta-b and Meta-f to go backwards and forwards using emacs mode in my shells. I'm noticing a number of non ASCII characters when I press these Option-b or Option-f.
I noticed in Mac's Terminal.app the option "Use Option as Meta key" checked resolves this issue. It doesn't resolve the issue in my "xterm" session though. I think I can remap Option globally in Preferences, however this would impact all Mac applications.
I see some posts referencing setxkbmap and xmodmap (issue is occurring outside of Windows though). I tried xmodmap per [this][1] post and keys are still not working.
$ cat ~/.xmodmap
clear Mod1
! keycodes 66 and 69 are the option/alt keys; assign them as Meta keys
keycode 66=Meta_L
keycode 69=Meta_R
! now tell X11 that the Meta keys act as the Mod1 (meta) modier key; that is, when they are pressed with KEY, it is the same as hitting M-KEY
add Mod1 = Meta_L Meta_R
$ xmodmap ~/.xmodmap
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 118 (X_SetModifierMapping)
Value in failed request: 0x17
Serial number of failed request: 14
Current serial number in output stream: 14
The keys output when I press OPTION-f after xmodmap:
$ æ
Pressing left option, shows mapping but it doesn't impact the shell behavior:
$ xev
