A shortcut for the Pause Button in Cycles

Do you think it’s possible to create a shortcut for the pause button in Cycles (when you render in the 3D View)?
I Tried to look for something in the prefs panel but I didn’t find something (and I do not make an error).
Thanks for your help.

No answer at all???

Setup a shortcut with
Context Attribute: scene.cycles.preview_pause

If you put this under the 3D View section you will have to have the mouse curser in the 3d view for it to work

When testing it, this paused the preview render correctly but did not toggle it back on again unless I mouse click in the timeline or mouse clicked on the pause button.
