I just installed Arch Linux on my Macbook Air, and I've been using Macs for so long that my PC keyboard muscle memory has all but deteriorated. In Mac when I type "special" chars like $, @ etc. I use the left option (or alt) key to do that. Now in linux (or Windows, for that matter) the right alt key gives me those chars and left alt is just a modifier key. Is there a way to switch those two?
xmodmap -pm output:
xmodmap: up to 4 keys per modifier, (keycodes in parentheses): shift Shift_L (0x32), Shift_R (0x3e) lock Caps_Lock (0x42) control Control_L (0x25), Control_R (0x69) mod1 Alt_L (0x40), Meta_L (0xcd) mod2 Num_Lock (0x4d) mod3 mod4 Super_L (0x85), Super_R (0x86), Super_L (0xce), Hyper_L (0xcf) mod5 ISO_Level3_Shift (0x5c), Mode_switch (0xcb)
