Short description of error
When you select a keyframe, Blender will automatically enter the grab operator.
This is detrimental to workflow as you have to hit ESC after selecting if you did not want to activate the move operator.
This occurs when selecting in the Graph editor, Dope sheet or the VSE.
This is the same with left click select or right click select.
Exact steps for others to reproduce the error
Select a single keyframe in the dope sheet and the grab operator will automatically be activated.
