Feature request: Add action to center viewport to position of the cursor

[felagund]

I am aware of View > Viewport following, but it does not suit my needs because:
1) It does not work with FastDraw plugin ( https://josm.openstreetmap.de/ticket/12663 )
2) even if it did, it leads to too many slow refocusing of the viewport after each click/placing of a node. Especially when I map curved features (meandering rivers, uneven forrest boundaries) I place the new nodes fairly close to each other. When viewport following is enabled, each centering takes almost a second. By that time, I might have already placed another node. Even if it were instanteous, my brain needs some time to understand how the viewport moved, so I would like to have control about the timing of the viewport refocus.

So instead, I would really appreciate an action (available as shortcut) that would move center of the viewport to the position of my mouse.

Now my workflow is:
1) Add new nodes by clicking (or using spacebar when using the fastdraw plugin) until I reach an edge of the viewport.
2) Right click, move the vieport by mouse dragging and go back to 1). It takes several seconds at least.

New workflow would be
1) The same.
2) Use keyboard shortcut, viewport refocuses, no mouse dragging needed, I go back to 1), several seconds saved.
