I just discovered something. I knew you can double click on a word and drag to start selecting by whole words, and this works across many apps.
But on my Linux Mint 21.2 system, Geany seems to be unique in allowing the following: * Click and drag on a word character, hovering over another word character * Then release and immediately click again Geany will extend the selection to include the whole of any partially selected words.
I expect the behaviour is part of Scintilla, anyone have more details, when it was added? I expect it isn't documented in Geany's manual.
This is useful when you start a normal selection and either: * you can't be bothered to double click (I avoid it sometimes as you have to be more precise (and I think push harder) with your finger and ensure you get the timing right than a single click) * after selecting most of the text you want, you want to switch to whole-word selection mode rather than keep dragging and be precise about where you release the mouse button.
So this gives another way to reduce the distance you have to move the mouse besides the initial double clicking method.
