Opening the Docked MIDI Editor
I've never used the Docked MIDI editor much because the floating editor is so easy to open using the shortcut Ctrl/Start+=. Until Pro Tools 12.8.2 there wasn't a shortcut to open the docked editor but now it can be done using Ctrl+Option+Shift+= (Start+Alt+Shift+= on PC).
Navigating And Selecting Notes
Using the left and right arrows in either MIDI editor or in notes view in the Edit window it is possible to step through the MIDI data note by note. By adding shift contiguous selections can be made.
How Is This Different From Using Tab To Transients?
A good question, and one I was asking, particularly as in Pro Tools 2018, Tab to Transients tabs to not off as well as note on events. The difference is what happens when Shift is used to create a selection. Using Tab to Transients an edit selection is created, using Shift+left/right the notes are selected but no edit selection is created so only the notes are selected, no midi CC data is selected as part of the time-based edit selection which selects everything within the selected time period.
