Since I've seen a number of people asking in the comments and couldn't find it written anywhere, I've decided to make a quick list of the achievements tied to this mod. Pretty sure I've unlocked them all, because the creator states in the mod description that there are 9 standard achievements and 1 shadow achievement. Without further ado, the list:

1. "Just This Once: In a Trigger Finger run, brute force your way into clicking the cookie."
-Pretty sure this one just requires you try to click the cookie several times. I used an external autoclicker, and it took a couple seconds.

2. "Rolling Around (at the speed of sound): Bake 100,000 cookies in one Trigger Finger ascension."
-Exactly what it says in the description. Bake 100,000 cookies while playing the mode.

3. "Infinite Scroll" - 1,000,000 cookies in one ascension.

4. "High Roller" - 1,000,000,000 cookies.

5. "Tenosynovitis" - 1 trillion cookies.

6. "Till the Wheels Fall Off" - 1 quadrillion cookies. Unlocks the heavenly upgrade.

7. "Rollin'" - 1 quintillion cookies.

8. "Reinventing the Wheel" - 1 sextillion cookies.

9. "Fastest Hand in the West: In a Trigger Finger run, have a scroll rate of 500%."
-Again what it says in the description, in order to reach that multiplier you'll need to simply buy the various "(Material) Mouse" upgrades, e.g. Plastic Mouse, Iron Mouse, etc. They give a boost to scroll rate in addition to the click rate bonus.

10. (Shadow) "Restraint: Bake 1 trillion cookies in one Trigger Finger ascension without owning more than 10 cursors."
-What it says in the description, now with extra suffering. Not much to say besides buy only 10 cursors at most, then be prepared for a bit of a long run. (From personal experience, I do NOT recommend trying this run at the same time as you try to earn the "Hardcore" achievement. That was extra painful.)

Hope this helps. On the subject of achievements, the ones from this mod will not unlock new milks if the achievement would push you over the normal threshold. I believe they do still increase your CPS according to any kitten upgrades you have.
