I am troubled
This macro does not act definitely

MACRO MBUTTONDOWN BUTTON_LEFT
TRIGGER F5
KEYDOWN KP3
MBUTTONDOWN BUTTON_LEFT

MACRO MBUTTONUP BUTTON_LEFT
KEYUP KP3
MBUTTONDOWN BUTTON_LEFT

MACRO MBUTTONDOWN BUTTON_LEFT
TRIGGER F6
KEYDOWN KP3
DELAY 77
KEYUP KP3
DELAY 30
MBUTTONDOWN BUTTON_LEFT

MACRO MBUTTONUP BUTTON_LEFT
KEYUP KP3
MBUTTONDOWN BUTTON_LEFT

Macro acts even if I do not push the left button
How do you recover?

This is because you defined the same macro twice:
The first macro stops the macro, and the second restarts it.
Remove the second one and it will work.

You could also have written something like this:
But it turns out it does not work because of a bug (issue 224).
