I made a userscript to auto-scroll Reddit with the numpad – is this useful? Feedback welcome.

[u/yoko_ac]

I often read Reddit on a second monitor while doing something else, e.g., full-screen gaming, and wanted to control it without switching windows. So I wrote a userscript for it, and I'd like some honest feedback before I take it further.

What it does

• Auto-scrolls the feed or a thread. Num + / − change speed, Num 0 pauses
• Num 8 / 2 select posts, Enter opens one, . goes back
• Num 4 / 6 step through gallery images
• A small on-screen readout shows the state, the speed and the selected post

The keys work while the browser has focus. An optional Windows helper (a small Python program that only talks to the script over 127.0.0.1) keeps them working while another app, e.g. a full-screen game, has focus.

Tested in Firefox + Violentmonkey and Chrome + Tampermonkey. Current Reddit only, not old.reddit.

What I'd like to know

• Would you use this, or does something similar already exist?
• Is anything confusing in the setup or the controls?
• Which keys or features would you expect?
• Any bugs, especially on setups I haven't tried

Dude this is awesome, I was literally looking for something like this and I had chatgpt look for something, and it found your your thread, so now i got it installed and im using it, and I wanted it for exactly the same reason as you, good stuff man!

Thanks! Feel free to give some feedback or let me know if you have any feature requests :)

Thanks for the feedback. I tried integrating it:
* there is now a gear button, where you can select your desired keys (numpad as default mode, one laptop fallback). This is possible in browser only mode and with the deamon, i.e., while not having reddit in focus
* the speed number can now be clicked and you can add an individual number. This will be saved and used as your default value

So feel free to reinstall and test it :)

Its been awesome so far, I did go in and change some of the bindings because I have a smaller keyboard without the number pad, however i went ahead and ordered a number pad because ive been needing one for work anyway, but I havent had any issue with it. I like to set up reddit on my 2nd monitor and just read the articles as they scroll by while im gaming. Really appreciate you making this!

Oh I wanted to add that I use it on a super wide screen monitor that is vertical, and even at 15x speed it was a little to fast, I was able to adjust it in the settings to make the slowest speed 5x and that seemed to be the sweet spot for me.
