Hi, I've been training Colemak for almost 3 months using an external mechanical keyboard with thumb for shift and backspace. I decided to transfer my skill to my laptop keyboard using EPKL and successfully set the wide angle curl mod. My only problem is thumb keys for shift and backspace that I got comfortable from mechanical keyboard. Here are the keys I need configured for my laptop keyboard.
tap the right ALT = BackSpace
hold the right ALT = SHIFT
Thanks in advance for the help
