In Snap!, GP and MicroBlocks there's a pretty powerful keyboard interface to assemble blocks. I use it all the time instead of dragging blocks. Check out page 115 of the Snap! reference manual here: https://snap.berkeley.edu/snap/help/SnapManual.pdf
Jens Mönig implemented keyboard input for both GP and Snap!, so the same hotkeys will work on both. Since we're using GP for the MicroBlocks GUI, the same will also work on MicroBlocks.
