I'm trying to change between the active buffer and the alternate buffer with the command Ctrl + ^ as this video explains. However, nothing happens. I'm using a Spanish keyboard and to press the ^ accent, I have to hit Shift therefore I have to type Ctrl + Shift + ^.
As I said nothing happens so is there any other way to do this or could I just map other keys?
Ctrl-V
in insert mode to find out what your keys are generating in Vi. See:h i_Ctrl-V
