It would be a huge time saver to have keyboard shortcuts for assigning markup statuses.
Numerous workflows (e.g. QA/QC and design reviews, punch/back-check) involve multiple status changes for markups, and often times there are multiple statuses (or state models) to choose from. On large projects, with 100's if not 1,000's of markups, all requiring multiple status changes, having to right-click a markup and navigate the status tree (or double-click and navigate in the markups list) is time consuming and cumbersome.
Having pre-defined keyboard shortcuts, or perhaps a way to create custom hotkeys for different statuses, would save companies hours of time at this scale.
