Sure, from the point of view of `define-key', it would be. What I meant is that key-handling right now is done on the basis of received events, and that "key pressed down" is not an event. We only have "key pressed". I don't know how hard it would be to break up key events into multiple phases, or how backwards compatible it would be to see a union of up/down phases as equivalent to what we know now as a "key press" event. -- John Wiegley GPG fingerprint = 4710 CF98 AF9B 327B B80F http://newartisans.com 60E1 46C4 BD1A 7AC1 4BA2

I think that if you can get the press and release of a key then you have access to all information from the hardware. Everything else can be derived from that. Kind regards Simon Friis Vindum

I was not able to find any such requests. The feature request: It should be possible to bind functions to the _release_ of a key. Additionally it would also be nice if it was possible to get the current state of a key. I.e. is it pressed or not. As far is I understand implementing this in the terminal is impossible=E2= =80=94so this feature would be for graphical environments only. Motivation: Here are a few ideas that I've wanted to implement as Emacs extensions. They all turned out to be impossible due to the lack of this feature. To implement them it would be necessary to be notified both when a key is pressed and when a keys is released. 1/ The possibility of bindings commands to the long press of a key. For instance I would bind a long press of `s` to `isearch-forward` and a long press of `n` to `avy-goto-line-below`. The extension would calculate this time difference between key press and release. And based on that decide between short- and long-press behaviour. 2/ An extension that would make it possible to use a regular key as a modifier key. For instance holding `j` with the right hand could activate "wasd" directional keys for the left hand. Or holding `a` could activate vim-like directional keys with "hjkl". The possibilities are many. 3/ Get press and hold behaviour independent of the OSs key repeat behaviour. If I bind a function (e.g. one that scrolls the buffer a single line) to a key binding then the behaviour will be like this: initial press scrolls one line. Then there is a long delay. After that a single line is scrolled with very short delays. It is controlled entirely by how key repeat works in the OS. Getting rid of the initial long delay or controlling the repeat interval is impossible. In my initial search for this feature I came across a bunch of StackOverflow questions that also asked for behaviour that would require this functionality. Often the best answer was to use key-chords. But the semantics of pressing two keys quickly after each other is quite different from the press-and-hold semantics of a modifier. Thank you for considering this.
