Investigate how to cancel multiple carets on move

multiple carets can be added at the $1 positions to edit the two values simultaneously. However, when moving up/down using keyboard arrows, all the carets move up/down. It would make more sense to disable multiple carets when keyboard arrow event happens but I'm not sure how to do it with Scintilla.
What happens is this:
- User selects autocompletion item
\begin{} \end{}is inserted and two carets are placed inside{}so editing happens simultaneously
- User is done with editing inside
{}so he presses arrow down to start editing the text in the block - what happens is this
where both carets still exist. What I'd like to do is to keep only the primary caret. How can I detect arrow key presses to cancel multiple carets?
There is SCN_UPDATEUI with SC_UPDATE_SELECTION that probably gets fired but I guess it also gets fired when the caret moves as a result of inserting text so it won't detect arrow presses only.
@nyamatongwe Any idea?
Alright, I think I could just intercept GTK keypress events and do SCI_CANCEL when arrows are pressed if there's not a better way.

Done this way.
SCN_UPDATEUI is less specific than key monitoring but there are many keys bound to actions which may need to cancel.
