looks like it's a duplicate of #53

It's a branch off the other PR but this one has an extra commit to keep the features separate.

I think this is confusing.

Are you suggesting that you would set up a keymap to trigger the first NES. then just go on a roll with auto triggers?

If so, then these variable names arent clear to me

It would be 100% manual when auto-trigger is false. The existing keymaps to accept the NES today would also be used to trigger the NES. So the first apply_pending_nes requests a NES, the second would apply it. If the user wants another NES, they would again call apply_pending_nes.
I can write a test or two if you would like to see it in practice!

I see now

A test would be great.
We can bike shed the option name after

I think in my head this makes sense flipped

So the option being
manual_trigger and false by default
