If you do not have the arrows on your keyboard, it is possible to create them with the SET KEY MACROS function in MacKermit.
I have place the keys like this using the COMMAND key with them:
[ is uparrow
/ is downarrow
' is right arrow
; is left arrow
For page up and page down, you use the OPTION key with:
[ is page up
/ is page down
For the 1, 2, 3 and so on, you simply use the COMMAND key with the specified number.
To view what is needed to generate a key simply use the SET KEY MACRO menu and type any key holding the COMMAND key at the same time. You will see the keys I have programmed.
