✨ Shift-Click to Make Text Selection

[austincondiff]

Users should be able to make a selection by holding down the Shift key and clicking anywhere in the document to highlight text from where the cursor was to where they just clicked.

This now works, but only half-way. It only works on the first click. When I click a subsequent time further down, it does not update the selection to include the additional characters/lines.

This works now, closing.
