Lubuntu ships with version 0.13.0 of Keyboard and Mouse.
Useage
------
To increase the sensitivity of the mouse drag the slider next to sensitivity towards the right or conversely to decrease senseativity drag the slider towards less sensitivity. To increase acceleration of the mouse drag the slider to the right for accelration and to make the mouse accelerate slower drag it to the left. The settings should apply immediately so make sure the mouse moves how you want it. If you do not like the new settings press the reset button to go back to your previous settings.
If you wish to only have to click once to activate buttons normally requiring two clicks check the single click to activate items checkbox. If you wish to swap left and right buttons on your mouse press the left handed button on the mouse. Note that this also swaps the button on a touchpad.
The cursor tab on the left lets you change your cursor theme which is quite useful if you are say running virtual machines so the cursor does not look the same in the host and the guest. To change a theme scroll down to which theme you want under preview but you will have to logout and log back in again for this to fully take effect.
To launch Keyboard and Mouse use menu -> Prefrences -> LXQt settings -> keyboards and mouse. In LXQt configuration center press the keyboard and mouse button and keyboard and mouse. From the command line run lxqt-config-input.
