Everywhere else on macOS, you can use option-left to move the cursor to the beginning of the word the cursor is in (including any punctuation attached to that word, but not brackets), and if you're at the beginning, it moves to the beginning of the word. Option-right does the same, but to the end of the current or next word.
Option-up takes you to the beginning of the line, or if you're at the beginning of the line, the beginning of the previous line. Option-down does the same, but to the end of the current or next line.
Command-left takes you to the beginning of the current line without the risk of overshooting if you double-click the left key, command-right takes you to the end. Command-up takes you to the start of the document, command-down takes you to the end.
However, Affinity Photo treats command as option, and option as changing the current selection's spacing, making characters closer or further apart on the X axis with option-left and right, and lines closer or further apart on the Y axis, with option-up and down. This is all very useful for typesetters, but I want text-navigation consistent with the rest of macOS without accidentally having to undo anything or be frustrated with it not working properly. Could it be a togglable option? Is it already one I don't know about?
Thank you for your time.
