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.
In a browser I right click on a bookmark folder to open all the bookmarks in separate tabs. I usually do this with my social sites.
To update Fedora “sudo dnf upgrade”. I used to use the software store but that often requires a reboot.
Windows+L to lock the computer.
I always have my vpn, terminal window, and qbittorrent start at boot.
