hi smallo and welcome to the group!

here's something you may find useful in keyclone: mouse-mapping

first: associate a key with a simple /assist macro

second: keyclone / setup / mouse-map

left click the 'mouse action' area... LBUTTON will appear
left click in the key area and hit your /assist key

click '+' to add it to the list

click 'ok'

now, whenever you left click on something, the click will translate into the /assist key... and the clones will get the target. depending on latency, you may have to click a second time.

you can use right,left, middle buttons as well as alt,ctrl,shift ... loads of mouse oriented actions to trigger a key... keeping your hand on the mouse and saving you the time of transitioning.
