Temporarily stuck with Notepad, I'd like to know if there is any better or quicker way of selecting from here to the end of the file than moving the mouse to the bottom of the screen and then vigorously from side to side (which is more exercise than I expect to get at a computer).
Place the cursor at the start of your selection then:
Ctrl + Shift + End
To select to the end of notepad.
FYI in OSX you have to use the alternative key command like so:
control + fn + →
This arose when I was remote desktoping into a Windows 2000 server from my OSX laptop.
In Microsoft Word on Mac, it took me several tries but this worked:
Shft + Fn + Cmd + Right Arrow
...to select to end of file and delete.
