Steam Deck helps you to automate all your routine button presses and mouse clicks (macro/macros) while playing.
Use "Move Cursor Relative" feature (25ms delay) to position mouse cursor exactly where you want automatically;
L4 click to Crouch (B button)
L4 hold (300ms) to Sprint (LStick click)
R4 click to Jump (A button)
Long story short: if you want to perform a few actions with a single click (type a word / click a screen area / move mouse cursor/ anything else really) - you absolutely can, just make sure you don't mess up action activators/delays (in ms). Also, if "delays" are tricky to nail down - split your algorithm in 2 parts by "Start Press" and "Release Press" activators.
Happy gaming to all of us!
