Hi Angel,

I hope I understand correctly what you are trying to achieve.

I believe Rosegarden does have a bunch of keyboard short-cuts in the 
notation editor which could aid you in this scenario, if maybe not 
exactly like that:

- Note entry through (QWERTY) keyboard. You may have noticed that 
keyboard rows are mapped to DO-RE-MI pitches in notation editor: e.g. 
a-s-d-f-j-k-l corresponsds to DO-RE-MI-FA-SOL-LA-SI
It takes a while to get used to it but can speed note entry quite a bit
- UP/DOWN arrows change pitch of selected notes up/down
- CTRL + UP/DOWN: change pitch of selected notes an octave up/down

- Note dureations: numbers (hint if you hover your mouse on a duration 
in the palette you can see the corresponding keyboard shortcut in 
parenthesis) e.g. 1/4 = 4, 1/8 = 8 etc.
- CTRL + corresponding number, will convert all durations of selected 
notes to the corresponding duration. Note that this will leave start 
times as they are, which may or may not be what you want depending on 
the situation
- CTRL + H and CTRL + SHIFT + H: rescale duration to halve/double: this 
will also *move* notes, which you may or may not want (different factors 
than double and half can be accesed from Adjust->scale menu)
- SHIFT + (left/right) Arrows select notes
- ESCAPE: unselect all notes
- left/right arrows, move cursor through notes
- CTRL + left/right, move cursor one measure at a time
- ALT + left/right arrow: move slected notes a 32snd earlier/later

- Not as extensive as note entry, but there *is* SHIFT + UP/DOWN arrows 
to increase/decrease velocity of selected notes (I think it goes in 
steps of 10) - the Adjust -> velocities -> set event velocities offers 
much more options

Hope this helps.
