Feature Request: Allow Editing of Points in Measurements

[billdenney]

Currently, it is possible to adjust points (tweak the position, etc.) in plot data. That doesn't appear to be possible with measurements, and it would be useful to be able to modify the point subtly rather than delete and regenerate.

Even with measurements, you can click on the points and move them around with the keyboard.

Would be nice to be able to accept keyboard entry of the coordinates of some points with known values in addition to the existing feature of manual adjustment.

For me, the adjustment of the position of reference points in the drawing plane discussed here spurs to suggest an addition: while currently they are moved with the arrow keys, it would be nice to move them equally by hjkl, like by muscle memory in the vim editor.

So, because the "j" key already has this little bump to guide the hand to the home row (and not only in layout of the US keyboard, by the way), "h" clearly indicates a move to the left hand side, etc. This is a pattern adopted by other programs (e.g., vifm) or plugins (e.g., vimium in Firefox, or as a choice in VS Code), too.
