Keyboard shortcut to change line width

[steve.ledger]

Or, while the line is selected you can hover your mouse cursor over the line control box and roll your mouse wheel to change line widths. No clicking necessary.

Thanks the additional advices,

Steve that method is great, that is faster than with the keyboard! Maybe I would wish once yet the possibility to determine the steps in smaller units, so for example after the 4px the 5px would come and not the 8px, but even without that is perfect
