Karabiner is almost too flexible. It let's you do almost anything, but it's so hard to configure it correctly. I use it for example to remap CAPS -> CTRL and CAPS + ' = `. Sometimes it just enables caps lock instead. Also, after few hours of use laptop starts to feel as if it's lagging. 1 key press will output multiple letters. The only solution is to restart karabiner every few hours. Anybody has any simple alternatives? Even if it costs a bit of money.
