Thanks for the replies guys. Richmond, sorry I was not clear. It is simpler:
- I click in a field that has a value - I press arrow key (up or down) - I want the value to change up or down in that field - After the value is changed, other actions are triggered, e.g. setting the value of a scrollbar to the same value - The process continues while I have the arrowkey pressed - As soon as I release the system is idle (except for the last arrow action that continues) It is the final action I have a problem with, as dozens of arrow key actions are held in the buffer. The number keeps increasing or decreasing and background actions are triggered. Here is a minimal version of the handler I have: on arrowKey theKey if theKey is "up" then put current_value + increment into the target end if -- up if theKey is "down" then put current_value - increment into the target end if -- down pass arrowKey end arrowKey On 1 December 2017 at 20:27, Richmond Mathewson via use-livecode < use-livecode@lists.runrev.com> wrote: > I may be a bit stupid, but as far as I understand you are trying to do > this: > > 1.
