Allow to set custom keyboard shortcut for tool size larger and smaller
If you have an AZERTY (French) keyboard it is IMPOSSIBLE to increase or decrease the tool size using a key shortcut. Allowing users to set a custom key would at least permit them to work around this limitation, at the same time as it would enlarge the customization of the tool.
With AZERTY the default keys [ and ] aren't accessible except using the Alt Gr modifier, and this does not work. This is confirmed after extensive searching by the community from a question I asked here: https://community.adobe.com/t5/illustrator/square-bracket-keys-on-azerty-touche-crochet-avec-clavier-azerty/m-p/11154730?page=1
Allowing to resize the tool with the keyboard is important for graphic work as the tool size is something you need to change often. As in graphics you need to use the mouse a lot, moving the mouse to the menu to change the tool size with the UI means you lose the place in the graphics where you were editing.

The same shortcuts that work in Photoshop are used with modifiers for Arranging objects
