@Pablo Vazquez (pablovazquez) This is now assigned to the D shortcut (D + mouse drag still enables the annotation tool). Is that OK?

Bohdan Lvov (ostapblender) added a comment to D7510: Object: Switch Object operator.

Is it possible to accept this patch as an operator without default key map?
It sounds like it is stalled by default preferences discussion that is without conclusion...

This tool sounds like little paper cut fix but actually this paper cut is so deep it almost cuts my arm off lol.
Going into object mode each time you want to switch object in the same mode either Edit or Sculpt mode is like running in marathon but some weird dog is jumping under your legs the whole time biting your ankles.
