single and double shortcuts

Hi, I would like to understand better why some shortcuts in Dorico are like they are. What is a logic is behind?

Some key commands are “single”, for example:
Chord input will be activated and deactivated with a single command “Q”.
Dotted Notes will be activated and deactivated with a single command “.”
Input of Slurs with “S” and so…
That is very convenient to work with and to remember.

But some commands are “doubled”? For example:
To force stems down - “W”, to force them up - Alt+W".
Tuplet input starts with “Alt+Ö” (German keyboard layout), and ends just with “Ö”.

Why not to use just consistently one command “W” or “Ö” to activate and deactivate such options? If user has in some bar stems down, pressing W he would get stems up and opposite. The same with tuplets - pressing “Ö” could activate tuplet input, pressing “Ö” again - deactivate it.

The idea is that you can choose to force stem up, force stem down or not force stem direction. A “flip” command wouldn’t work in that line of thinking.
Likewise, if you have an on/off button for tuplets, you wouldn’t be able to create nested tuplets without some further, more complicated options that you simply don’t need as it is designed now.
Anyway - apart from that, if you don’t like the shortcuts as they are, you can change them to suit your personal taste. I think it’s obvious that the default shortcuts are designed for an English keyboard layout and a laptop (no numerical keyboard) environment. Those of us with other languages and/or a big keyboard can benefit from a little tweaking.
