Right alt/option key on macOS setting different to left one possible?

[james-gonzalez]

On my iTerm2 terminal, I have the following settings for my alt keys, which give me everything I need.

I want to be able to use alt/option to for example do. alt + 3 == # OR alt . == (would toggle through the last arguments/params I passed in the previous commands)

Is this possible in Kitty?

The only option I see is macos_option_as_alt yes/no

Can you somehow make a new option to distinguish between the left/right alt/option keys?

Thanks!!!!!

I'm afraid this is too much work for me, sorry. But patches are welcome.

Actually on second thoughts there might be an easy way to accomplish this, I'll look into it when I have a moment.

@kovidgoyal - That would be amazing and would allow me to use this terminal as my main terminal.

Right now I have problem with this as I cannot enter national letters due to fact that Kitty register RALT and LALT as the same characters and do not handles them via the OS, which mean that I cannot enter letters like ą (RALT-a) in the terminal.

[kovidgoyal]

Simply set macos_option_as_alt to no in your kitty.conf

Still it, this cuts me from all ALT chords. Ideal would be to use one ALT as Escape code prefix and second as a AltGr.

@hauleth Not sure if this is acceptable to you (not the "ideal" case I guess), but as I only use Alt+b|f|t the following works just fine for me:

map alt+a send_text all \u0105
map alt+c send_text all \u0107
map alt+e send_text all \u0119
map alt+l send_text all \u0142
map alt+n send_text all \u0144
map alt+o send_text all \u00F3
map alt+s send_text all \u015B
map alt+x send_text all \u017A
map alt+z send_text all \u017C

map alt+shift+a send_text all \u0104
map alt+shift+c send_text all \u0106
map alt+shift+e send_text all \u0118
map alt+shift+l send_text all \u0141
map alt+shift+n send_text all \u0143
map alt+shift+o send_text all \u00d3
map alt+shift+s send_text all \u015a
map alt+shift+x send_text all \u0179
map alt+shift+z send_text all \u017b

@robertnorenberg Thanks for the tip! I never use alt for "unicode symbols", but the key is required for normal symbols like []{}|\$@ with my keyboard layout. This is the setup I am trying out right now:

macos_option_as_alt yes

# combinations where I want the "option" behavior
map alt+2 send_text all @
map alt+4 send_text all $
map alt+7 send_text all |
map alt+8 send_text all [
map alt+9 send_text all ]
map shift+alt+7 send_text all \\
map shift+alt+8 send_text all {
map shift+alt+9 send_text all }

# readline bindings I can't type with this layout
map alt+' send_text all \x1b*
map alt+plus send_text all \x1b?

Unfortunately (emacs/readline) prefix arguments aren't possible with this configuration. Maybe it's time to learn to use a US keyboard...
