Then, here are some of the customizations you can make -- I've listed mine, and you, of course, will make your own choices: Right click Desktop to open Personalize Scroll down and select: MOUSE POINTERS; this opens MOUSE PROPERTIES page. Go to: BUTTONS BUTTON CONFIGURATION Select: Right-Handed (or Left-Handed if you’re left handed.) DOUBLE CLICK SPEED: I set the slider to the slowest setting (if too fast, double clicks won’t open files) Click Lock: No POINTERS: Scheme: To make pointer larger, select Windows Standard (extra large) Customize: Select other pointers (hour glass, etc) POINTER OPTIONS: MOTION: Select a POINTER SPEED: I set mine at the fastest – makes the touchpad fly (This technically controls the mouse buttons, but makes also touchpad feel faster) Check: Enhance pointer precision In the Visibility section, check: Hide pointer while typing DEVICE SETTINGS: Click the Settings bar: Click on Overview to open the tree and read the overview of the controls. TAPPING: No BUTTONS: Double click on Buttons to open the tree and set the controls: Left ButtonAction: Primary Click Right Buton Action: Secondary Click VIRTUAL SCROLLING: Double click on Virtual Scrolling to open the tree and set the controls: Check: Enable vertical scrolling and horizontal scrolling LONG DISTANCE SCROLLING Coasting: No Edge motion when scrolling: No SCROLLING SPEED: Set slider for scrolling speed. I set mine at the slowest Adjust SCROLLING REGION SCROLLING SELECTION: I checked: Scroll item under pointer (for a broader scrolling area) EDGE MOTION: Select the Edge Motion you want. I chose Perform Edge Motion when pointing and dragging Select your Edge Motion Region and Edge Motion Speed. I selected: Control motion with finger and set my slider at medium-slow. Constrained Motion: No Slow Motion: No Sticky Borders: No SENSITIVITY: Double click on Sensitivity to open the tree and set the controls: Double click on + to open tree PALM CHECK: I left my Palm Check at the default spot, near center but a little toward Maximum (If mouse gets erratic, increase toward Maximum. If mouse is not responsive to certain clicks, decrease toward Minimum) TOUCH SENSITIVITY: Light Touch – I set my toward the most sensitive -- all the way toward Light Touch Click on Apply, and then OK.
