Assigning mouse button with shift to a key

[Kalju]

Hello,
I would like to assign “shift + middle mouse” to a key, but can’t figure out how to do so. when assigning a mouse button to a key, there is no option for modifiers, and when there is the option for modifiers, there is no option to use a mouse button.
i tried assigning Lshift and middle mouse presses in a macro, but i don’t think i’m getting the behavior I want (left shift and middle mouse pressed as long as the assigned key is pressed).

i found this question:

Send mouse key + keyboard modifier?

Hi, I’m trying to let my UHK (v2) send a (left) ctrl + right mouse button click. My current macro looks like this: pressKey LC- pressKey mouseBtnRight releaseKey LC- But this doesn’t seem to do it (I have an app that shows a context menu on its toolbar buttons with such a click). Is the macro wrong or what am I missing here?

but it is for a click, not a hold-while-the-button-is-held.
is it possible to have a macro that responds to keyboard behavior, or is it always a set sequence of inputs?

i’m mainly trying to have a single key press for panning in blender (which is shift + middle mouse). as an alternative solution, i tried assigning mouse 6 to a key and to pan in blender, but holding down the key did nothing (i don’t know if the issue is on the blender side or the uhk agent side).

any help would be appreciated.

This should do the trick:

pressKey LS
holdKey mouseBtnMiddle
releaseKey LS

(I am wondering if holdKey LS-mouseBtnMiddle is legal and supposed to work. If not, it should probably throw a validation error.)
