• Single click - cursor position
• Double click - word selection
• Triple click - paragraph selection

All three work with click + drag to select a range.

• arrow left, right, up, down - cursor movement
• page up and down - move cursor up and down a page
• home - start of line
• end - end of line
• backspace - delete previous
• del[ete] - delete following

Shift and Ctrl serve as modifiers to the above character and line based actions.

• hold shift - select text from cursor source to end
• hold ctrl - expand character action to word action (arrow keys, backspace, delete), line to full text action (home, end), and paging to tabbing

In programming, this can become even more fun with multi-cursor editing, where you can place multiple text cursors, and edit multiple lines simultaneously.

That does not make much sense for prose text, but regularly so for software source code which has a much more structured and sometimes repetitive aspect to it.

There are also many other operations like moving, cutting, and pasting entire lines without the need to select them.

Or scrolling the view while also moving the text cursor and selecting - or a view that automatically scrolls when you come close to the edge - so you don’t have to select then scroll then continue to select.

I regularly use an expand selection action that selects outwards. Word -> sentence -> paragraph. In programming with structured and hierarchical text this makes even more sense. variable -> parameter -> parameters -> function call -> function call statement including qualifier/scope etc.

• Select words with ctrl + shift + left/right arrow keys

• Select a character at a time with shift + left/right arrow key

• Select entire line with shift + up/down arrow key

Is this a Windows OS thing or does it work with Linux based Ossa too?
