Mine is using the arrow keys to navigate typed text while writing and editing. It helps speed things up, versus having to move your hand to the mouse to navigate.
Use the Up and Down Arrows to move/jump vertically.
Left and Right Arrows to move/jump horizontally.
Combine Left or Right Arrow with Shift to be able to select text. Use Up or Down Arrow with Shift to quickly select whole/nearly whole sections of text.
Combine Control with Left/Right Arrow to jump whole words to more quickly move to where you want to type.
What’s the point of the VPS?
Mainly to keep my end devices appearing to connect to a VPN in the same country. I usually do that especially when I travel to other countries that seem to block WireGuard leaving their borders.
I suppose if I had fiber at home I’d do it all there but cable internet’s slow 30 Mbps upload speed along with constant power outages make it a no-go.
