About this tool
This page opens the mouse tester with the right-button counter highlighted: right-click anywhere in the test area and every press lights the right side of the mouse graphic and increments its counter.
Normally the right button is hard to test because each press opens the context menu. Inside the test area that menu is suppressed, so you can click as fast and as often as you like and compare the counter with the number of physical presses you made.
If some presses do not register, try clicking different corners of the button — a switch that only responds under firm center pressure is wearing out. And if the counter jumps by two on single presses, check the interval log: that is switch bounce, the same fault that plagues left buttons.
Example. A left click increments the left-button counter, and a second click of the same button sooner than 80 ms is logged as suspected switch bounce.
Limit. Only left, middle, right, back, and forward buttons are tracked, and the event log keeps 20 lines.
