Add different modifier or permanent pen selector keys

[itcultus]

I find it very counter-productive to use the modifier keys.
In my setup I use a pen-tablet and using multiple modifiers for different pens means that I need to press buttons either on my tablet or in my keyboard every time I need a different color or a different shape.

What I would like to have is "proper" key-bindings, like:

Pen A is assigned to default pen
Pen B is used when I press the combination button Ctrl/Meta/Alt/whatever+B
Pen C is used when I press the combination button Ctrl/Meta/Alt/whatever+C

At the same time, great functionality, like for example the arrow, could/should be using Shift/Alt/Ctrl/Meta since I would like to have the arrow as an addition to my existing annotation's color, or the laser functionality requested elsewhere.

This will make my life enormously easier. For example, if I annotate on a dark background, I want to use Pen C, always. That means I have to press a key until the scene is changed to something else and I change pen's color altogether.

I would love to actually see this implemented.

I came here looking for this functionality, I clearly second the demand for the use case.

I third it. Currently trying to think of a way to add more colors while retaining three possible pen sizes, and it would be incredible if I could just set a pen, rather than having to hold modifiers, that are limited.
