Key combinations:

{#Shift_L(Left)} (considered a {#Left}, should select the character on the left) -- in most applications.
{#Control_L(u)} (considered a {#u}) -- only in TeamViewer in remote computer mode.

Hacker's keyboard can send all of these combinations without any problem (and have the expected effect).

Perhaps this is caused by something that the application cannot handle too fast keys sent properly?

Looking at the source code, I observe that:

The time stamp for the key down and the key up event are identical.
There's no key event sent on modifier key down/up (only the modifier mask changes) (confirmed that Hacker's Keyboard does send shift down/up events with KeyEvent Display)

Looks like adding key events for the modifier keys fixes it for {#Shift_L(Left)}.

Can you push the modified code somewhere? (if you don't want to make a new release immediately...)

The mentioned patch fixes the TeamViewer issue too.

nimble0 commented 3 years ago

Excellent, thanks for the report.

Were the fixes integrated?

nimble0 commented 6 months ago

Yes, v0.3.1 includes those fixes.
