i want to make shortcut for wire displaying (not wireframe mode, displaying wire on top of solid mode), you can find it in the Properties window> Object tab> Display. when i right click there is no "add shortcut" option
Donwload the "Display tools" add-on and assing a shortcut to the "wire on" option
This allows you to apply effetc to multiple selected object at the same time.
This is a way in wich you can hack the problem.
I've found a bit tricky solution, but it works. It's based on keyframing and allows you to switch between desired modes using right and left numpad arrows.
Go to frame 0 and press I while hovering the cursor over the Wire box in the Display panel of the Object header.
Now go to frame 1 (press →), check the Wire box and press I again. Now you may easily switch between solid and wire modes using left and right arrows.
