Click, Shift-Click selections
Click somewhere in this post. Move the cursor somewhere else in it. Shift-click. Intermediate text is selected!
Just found out about this a couple of days ago. It’s always weird and somewhat shameful to learn so late something so basic but by the same token it is always oddly exhilarating. Seems to be particularly useful in cases where click-holding selection becomes unwieldy: when long fragments have to be selected or when a crappy touchpad is the selection tool. (-Seems to work only on Windows so far.- Seems to work on Windows and Mac so far.)
