Change noteinput direction up/down in Key Commands, possible?

To change the direction for note input I can use shift+alt+“note” for up
and ctrl+alt+“note” for down.
Is it possible to change that in Preferences->Key Commands?
I rather have only one or keypressure since it´s something i use a lot.

Also. If I’m in NoteInput is there a way to change the pitch right after
input the same way a chage pitch in Write?

You can change the shortcuts assigned to Lower pitch by step and Raise pitch by step in the Note Editing category in Key Commands in Preferences.
