This mod offers two distinct things:
- bind a key to do "Trigger Now" a timer block or to "Run" a programmable block.
- an API for programmable blocks scripts to see what keys are pressed - which is not relevant if you're not writing a script.

For using it with a timer block, vast majority of the setup is identical to doing it without the mod. If you're not familiar with timer blocks: https://spaceengineers.wiki.gg/wiki/Timer_Block

The difference is at the end:
- without the mod you'd add the timer block's "Trigger Now" to a cockpit/RC toolbar and press that toolbar slot.
- with the mod you can instead add an input on the timer block and when you're in a cockpit/RC on the same ship you can press that.

The complex part is the programmable block API which allows scripters to read inputs from inside the script and do a plethora of things.
