Is there a fix for this? I’m not particularly adept at the more technical stuff, but I’m sure there has to be a quickie way to get to the end of a long document.
Most possibly you are working on a notebook.
Check if the words Home and End are printed in the keycaps with other color, the same of a Fn key.
If when you press End, it only move the cursor one character/space to the right; and if when you press Fn+End, it move the cursor to the right of the line, you will need to press Fn+Ctrl+End to get to the end of a document.
