Windows Mouse and Keyboard – How to Simulate Left Click and Hold or Rapid Left Click

You should be able to achieve this using BetterTouchTool. It's an app you'd have to install but it's free an has lots of other useful features. You can also choose to limit this functionality to a single application or use it globally.

You could use xnee to record your mouse action and replay it later when needed.

There's a gui for it called gnee. I didn't have very good results with it last time i tried but that was a long time ago, things might have changed since then.

Here's what i used for the recording:

$ sleep 2 ; xmessage ready ; sleep 1 ; cnee --record --mouse --keyboard -o cnee.data

This lets you move around and prepare things before starting. Click ok when you're ready, wait 1s and do your action. Ctrl-c when you're done.

Then you can replay it with:

$cnee --replay -f cnee.data -v -e /dev/null -ns

You can even replay it faster than the original (!)

$cnee --replay --speed-percent 40  -f cnee.data -v -e /dev/null -ns

You'll probably have to edit out the end of cnee.data to get rid of what you did in between your action and the Ctrl-c.
