Hello

Since I have been used Vaa3D in manual neuron tracing and worked with experienced annotators for half a year, I'd like to share some short keys which was frequently used and proved to be time-saving and effective.

1）Alt-N: Highlight the drawing curves without breakpoints.
This function could be used in the process when you were to be finished annotation and helped you to quickly check whether there were missing segments/breaking point or not.
2) Alt-N+D: Delete series of drawing curves highlighted.
This function could be very helpful in the manual tracing correction process, it can delete all segments under the wrong branch.
3) Alt-T+shift / Alt-D +shift: Retype/Delete multiple neuron-segments in batch. Drawing a circle to circulate the segments to be deleted by holding on the shift key.

Hope that helpful, and anticipate to be supplemented.
