to_after_keyup_till_not_alone

[negentropi]

what want achieve:
single letter key as hotkey when hold above 250ms.

what problem:
when u from e to after keyup e, then u findout have a delay that not from karabiner but from waiting u keyup so it send e so when u type 'eu' in that mode u find out mostly it type 'ue'. cuz u are keep holding the e while u already preese down the u, so thats why need to have 'untill_not alone' to make it just before the u is down then the e should already releaste make sure was eu while didnot trigger when just alone .

this not need to say if it was go beyound like hold a that is a layer, so aw equal to cmd w etc. it even would need lot more precise control over each hw input. if not it would just become im just typing aw or im doing hotkey

You can achieve this by combining to_if_alone and to_delayed_action, so please try the example on this page.

thx for reply.

first i want to ask a new question
undo_prior_key, keyup_oder.
can undo a key was send really help to develop hotkey around letters, and by have a specify oder resolve conflict to typing eg key a always should be the first keydown and the last one keyup.

back to thread.
those wont work becuz i need fulfill those in the same time
i.require to be alone() during the key hold.
ii.set the held duration
iii. trigger on after keyup.

Since it's not possible to cancel a key once it has been sent due to how the system works, we would need to introduce a mechanism to defer key sending. However, it's unclear whether that would actually solve the problem, so could you share a bit more detail about what you're trying to achieve?

on oder:

• a keydown then f keydown then f keyup to action and cancel the a and f.
• a keydown then a keydown then e keyup to action and cancel the a and e.

Is this similar to what's described in this issue?
