Improved caret behavior on first and last lines

[bobbylight]

Describe the solution you'd like
On macOS, pressing the Up arrow while on the first line in a text component typically moves the caret to the beginning of the first line. Similarly, pressing the Down arrow while on the last line moves the caret to the end of the last line.

Are there any workarounds?
Ctrl/Cmd + Left/Right Arrow as appropriate
