Mouse double click speed

Trouble like me with Mouse double click speed?

Google “lxde double click speed”, there is a hidden file named “.gtkrc-2.0” in your home directory. So if it does not exist, create it. If it does exit, read it before you proceed — it may advise you to use “.gtkrc-2.0.mine” instead.
Type these commands from the prompt, or inside LXTerminal.
