I am using Xubuntu 18.04.4 LTS on a Lenovo ThinkPad W530.

If I do not not hit a key exactly, it may happen that more than one character is recognized. In general, the first keystroke that is meant is the meant one, but the neighboring key which may have been striped one follows it.

Therefore I want to suppress the second recognized keystroke of an adjacent only striped key. I assume that his signals appears a few ms later, but the minimum value 50 ms in *slow keys* and in *bounce keys* are too long for my purpose. (For a person with shaky hands larger values are useful, of course, but for the application of a laptop keyboard with relatively short strokes, where you easily trigger an adjacent key with, this function would also be useful for non-handicapped people - if only the limit were not so high. Of course, they can also be applied for keyboards with bouncing contacts). 

This change is probably very simple to implement: just lowering the constants determining the lower bound for the minimum ranges of the two sliders. I think 10 ms would be a reasonable lower bound for both settings (with some margin). I would would probably choose something in the range of 20 ms for a myself. For handicapped users, the presently available values are ok.

For handicapped people it might be of value to have a *checkbox to let the system beep* in case a second keystroke is suppressed (either on the same key or on another one - in many cases probably one in the vicinity).
