This is not yet exactly existing but you have that!

Make a shortcut of this

script:/* Transparence */ var gd = moi.geometryDatabase; var so=gd.getSelectedObjects(); if (so.length>0) { so.setProperty( 'displayMode',1); so.setProperty( 'selected', 0); } else { gd.getObjects().setProperty( 'displayMode',0); }

Just select an object (s) and press the shortcut key!
It can be done on different objects!

Repeating the shortcut key will cause all objects to reappear!

So always select an object before calling the shortcut, otherwise it will cause all objects to reappear!
