One quirk about the G700: using the Logitech drivers, the scroll wheel doesn't work in "Microgear mode" (in which a tiny motion of the scroll wheel sends a scroll action). Instead, only a larger movement of the wheel (a full "click" in clicky mode) will sent a MWHEELUP or MWHEELDOWN command. To enable Microgear mode, you need to load a generic mouse driver. But to program the mouse, you need Logitech's driver.
Unlike the regular SetPoint software, Logitech's gaming mouse software doesn't let you enable smooth scrolling for all apps. The best you can do is use Microgear mode and set Windows to scroll 1 line at a time.
For smooth scrolling in web browsers, you can use either Logitech's
Scroll App or
Yet Another Smooth Scrolling/
Chromium Wheel Smooth Scroller. You can play around with the settings.
My recommended button assignments:
Thumb buttonsFront-top: Shift
Rear-top: Backspace
Front/bottom: Ctrl
Rear/bottom: DPI Cycle
This lets you go forward/back (Shift+backspace=forward) while giving you a shift key for Shift+Click. It also lets you use Ctrl+mousewheel for zooming, which has a "pinch-to-zoom" feel to it. If you use Photoshop you'll want to assign one of these buttons to Alt, or create a custom profile for Photoshop.
The rear/bottom button is one I sometimes hit accidentally, so I assigned it to adjust the dpi instead of giving a command.
Top buttonsTop: Paste
Center: Copy
Bottom: Ctrl+W
The copy/paste buttons aren't really necessary, but they save you a click. Ctrl+W is the close tab command. This is REALLY handy if you use a lot of tabs.
Tilt right: Ctrl+Tab
Tilt left: Shift+Ctrl+Tab
Once you use the wheel rocker to change tabs, you will never go back. Think you've lost right/left scrolling? Just use Shift+Scroll wheel (conveniently assigned already)
Center top button: application switch or Enter
For one-handed control, having an enter key is useful. This lets you, for example, copy and paste URLs and other text and hit enter with one hand. I put it on top so I don't accidentally hit it. Recently, though, I've been using it for Flip 3D.
Enjoy your G700! It's my favorite mouse.
