What does this script do?

This script allow you to use your mouse keys to scroll on page. No more need to move your mouse over scrollbar and drag it. No more issues with horizontal scrollbar on Chrome (when it hiding and not appearing).

All what you need is simply click and hold any mouse hotkey (default RMB) to start scrolling. To stop, simply release mouse hotkey. You still will be able to select text (LMB) and open context menu (RMB).

Settings

Variable name	Description	Values	Default
hotkey	Toggle hotkey	LMB: 1, RMB: 2, MMB: 4, HistoryFwd: 16, HistBck: 8	2
speed_multiplier	Speed multiplier (per pixel). Use negative value if you want to inverse scrolling direction.	±inf	1.5
allow_text_selection	Allow text selection when hotkey is LMB.	true/false	true
use_alternative_key	Enable alternative key mode. This mode allow you to hold another key (if your main key is LMB, then alternative key is RMB, in other cases it LMB) to further modify your scrolling speed. It can be either faster (if multiplier > 1) or slower (if < 1).	true/false	true
alternative_key_speed_multiplier	Alternative mode speed multiplier. If > 1 then increase speed, if < 1 then decrease.	±inf	5
inertia_mode	Enable inertia mode. Basically it allow you to continue scrolling after you release button in case your last scroll was fast. Similar functionality have any touch devices (mobile, tablet, e.t.c.).	true/false	false
inertia_friction	Friction/negative acceleration of inertia. Smaller value will make inertia longer and further and vice versa.	0 - +inf	1.75

FAQ

Why no auto-scroll on MMB? Or what the difference?

Auto-scroll	This userscript
Clicking MMB just activate Auto-scroll mode	Clicking hotkey prepare to use scroll, but if no movement is made, it cancel scrolling and you open menu on RMB instead or navigate via Forward/Backward history buttons or even activate MMB Auto-scroll
Auto-scroll create ±12px area around clicked position and you need yo move mouse beyond it to start scrolling	You can move mouse even on 1px to start scrolling
To achieve confortable speed you need to move mouse to proper distance, while in the process scrolling will be accelerated	Scrolling speed is fixed, however with alternative key you can change it to faster or slower rate
After you setup correct speed you may preserve it (cruise effect)	You will need to move your mouse manually by hand and speed affected only by you
To cancel you need to click MMB again or hold MMB whole time	Just release hotkey button to cancel

Overall time for shorter scrolls smaller for userscript. To human mind will be easier to work with fixed scrolling speed, as mouse wheel do, however mouse wheel typically slower, than speed we need. You still may use MMB in both cases if you want to scroll pages at constant speed (cruise effect).
