I wonder if it’s possible to change the behavior of a button by keeping it pressed down for longer. in particular, I wonder if one might hold ‘q’ for a second in order to emit ‘Q’. Completely removing the need to touch the shift key. I have an ergonomic reason for this because I am trying to limit the use of my pinky as much as possible.
It is possible. But I do not recommend doing this. Believe me, especially if you are touch-typist.
Try “press key” + “some other key” simultaneously = other action. In this case no matter how fast you type, it will work (better than long press).
Using Autoshift is an option, but will slow you down (when you are a fast typist). Another option is to use a key or easy to reach key combo (best one on the left and right side, to be able to alternate with the character key ) and assign oneshot Shift to it. Then you do not need to hold that key to get the shifted character/ symbol.
Home-row mods is an option as well. Did forget to mention those, because I could not get them to work fine. I use a custom layout where the home-row has a high amount of rolls, that did interfere with the home-row mods and led to false triggers. For a qwerty keyboard that is likely less of a problem I guess. I think key combos have a better chance to get them working correctly. But have not tried it with the UHK yet.
