On a different programmable keyboard, with a more traditional staggered layout (the ErgoDox has a columnar layout where where keys are aligned horizontally) I used that same function but on Caps-Lock, left of A: press it combined with another key, it is CTRL; press it alone, it is ESC. Programmable keyboards offer so many improvements, it’s incredible. Some of that can be done with xinput on Linux, but as far as I know the different-key-when-held functionality is not available there. [Edit: yewenjie’s comment mentions keyd which apparently does have that feature! https://news.ycombinator.com/item?id=31146572 https://news.ycombinator.com/item?id=31146572] While I waited for this one to be delivered (was a crowdfunding campaign) I used that to simulate some of its features and surprised myself when I found out that I stopped using the dedicated cursor keys even if all my keyboards had them. I had never thought of using J for CTRL. You lose the ability to enter Line Feed (Return) with CTRL+J which I do use from time to time, but it sounds intriguing. I might try it out one of these days.
