The Autoscroll Bookmarklet
Bookmarklets are actually a cool little concept – make a link that runs a JavaScript command and inject code into any web-page. Brilliant! Combine this with an obsessive computer nerd with some free time on a Saturday evening (for example, me), and you get following:
Autoscroll – The Bookmarklet
Works in Safari and Firefox. If you’re lucky it might work in Opera, Camino, and Konqueror. If you’re at least as lucky as this guy, it might work in IE.
Usage
Click the really big link above to activate auto-scroll (you may want to make your window small enough to have significant scroll space
Here’s the buttons to push:
| 0-9 | : Set scroll speed, 0 being stand-still and 9 being skim-speed |
| – | : Decrease speed |
| = | : Increase speed |
| shift + – | : Decrease speed quickly |
| shift + = | : Increase speed quickly |
| q | : Quit |
Installation:
If you’d like to pack this sweet action with you, drag the “Autoscroll” link to your bookmarks tool bar.

Nice. I wasted a few hours trying to get firefox or opera to scroll for a telepromter. Now I can click and go, while adjusting on the fly using a keyboard.
Thank you! Since I can't use a mouse, Firefox's native autoscroll function is inaccessible to me. But now I can click the link with Mouseless Browsing, and there it goes. Beats losing a keyboard key to an AutoHotKey script.
Hey, I'm certainly glad you found it useful! Thanks for stopping by :)
I saw your post about Dragon's inability to middle click... bummer. I'm a big fan of DNS myself, and am considering either buying MacSpeech, or upgrading to 10 and staying with Parallels. How do you like DNS 10?
FYI, this script has saved me from tendonitis. I use it daily. Thank you.
Thanks. Really useful.
Gracias Awesome setup/play...

This is great. Thanks so much!
What a good bookmarklet it is! But it doesn't work in iPhone safari. Prease make it for iPhone!!!
I was looking for a way to slow down auto scrolling using a mouse and found this site. This is exactly what I wanted but using the keyboard. I see lots of queries regarding this but no similar answers for mouse control. Thanks for your efforts. There is obviously a need for this to read on line.

Tim,
I use your this bookmarklet daily and was curious how to modify the code such as to set a new default scroll speed.
Thanks for making this available.
Best,
Tom
Hey Tom,
The source code is in there. It's a bit encoded, but with a little bit of effort you could decode it easily. Then search for a bookmarklet encoder to encode it back up again.
The speeds are there at the top. It's an array of [pixels to move, delay between movements]. It's using a logarithmic scale, doubling the amount of pixels and the delay every time the delay goes below 25 (browsers tank at that threshold).
Found it. Somehow I'd missed ss_speed variable in the URL encoding, so I wasn't understanding how you set the default scroll value.
To those who want to do likewise, just change "ss_speed=1" to whatever predefined speed you want. The number corresponds to the scroll speed key you'd press on your keyboard.
Best,
Tom
Esc does not seem to work. 0 stops scrolling. Esc does nothing. Not sure what it's supposed to do. Running Snow Leopard, Safari, on a Mac Pro.
hmm... it used to :S Maybe Safari changed the keycode sent by escape.
At any rate, been thinking about mapping it to Q as well.
Nicely done. Tweeted and FBed.
Brilliant! What an incredible time saver. Used in conjunction with Readability (both recommended by ScreenCastsOnline's Don McAllister) your service is truly enchanting.
Please help me out.I've been enjoying using this bookmarklet! My question is, how do I start scrolling without using the mouse? I was searching for the answer to that, to no avail...Mouseless Browsing does not help with a bookmark...or, at least I could not find how to do that... Anyone, help me start scrolling with keyboard?
@everevolving:
You could just assign a keyword to it: just open the bookmarks manager, select your bookmark in the bookmark toolbar folder, expand the little arrow to get more options, and type "as" under "keyword".
With this setting, whenever you type in "as" in the address bar, auto scroll will get invoked.
There may be a better solution, like some Firefox plug-in that enables you to set hotkeys to bookmarks, but without any additional extensions, this should do the job and allow you to activate it without having to use the mouse.
Hello Tim,
Can I use this script in a Firefox Add-on? Also could you contant me via cotcaro (at) gmail . com
I love this. Thanks to 30DCplus for this great tip
Thanks! this will be great for reading drum tabs while playing.. heck any tabs at all
IS there a way where once it gets the the bottom if a webpage to automatically return to the top and scroll down again? Like a looping scroll?
not without modifying the source code, no. However, with modifying the source code, the sky is practically the limit.
Can it work on an iPad?
Richard
@Richard - you'd probably need to modify it to work on an iPad. I mean, it might work as is if you hooked up a bluetooth keyboard. It's the lack of a keyboard that might be a problem.
Very useful, can this code run on an onclick event of a button in a web page; example;
[script]
function autoscroll()
{
your code here
}
[/script]
[body]
[input type=button onclick='autoscroll()' value='scroll this page now']
my page
[/body]
I tried copy/paste of your code but no luck.
@Unknown - the code is encoded for a link, so it won't work verbatim. If you de-url-encode and remove the hyperlink ceremony it it should work.
Also you could paste it verbatim in a link tag, <a href="
%code-here%>Click to scroll</a>
Just came here to say thanks!!! It's a great little too for what I need. I want to add this on my site (mostly older literatures) for people to read without scrolling, any chance I can get the source code?
Sure: https://gist.github.com/4062111
Just wanted to say thank you.
I spent several hours looking for an ereader for Windows desktop that would do exactly this, as the majority of my ebooks are in html format.
Instead, you gave a solution that I don't even have to download an would work for ordinary websites too.
Thanks again!a

What a great tool! I will be using it regularly. Thank you very much. It also works well on Chrome. Is anyone aware of a similar tool for ios mobile safari/chrome?
Thanks again.
Thanks it's good to see non greedy people, you are blessed. I walk my clouds for heaven on earth. I'll remember you. Luton, UK. Peace be with you!
