Check in the controls in the options to make sure right click does what is supposed to do, if it is but still is not working, then your mouse may have a dodgy right mouse key.
Right click on your mouse
Minecraft 1.5 and earlier: Right Click Minecraft 1.6 and newer: Left Shift I am guessing you will be playing a new version, so press shift. If that doesnt work, right click.
you've probably corrupted your minecraft. at the login screen click ''options'' then click on force update. After that you should be fine. Good Luck! :)
Re instull Minecraft
right click to open/close it will also work with redstone.
You right click, you're obviously doing something wrong.
They don't.
The shift click support always stays as shift and cannot be changed.
Simply right-click(or whatever the right click is configured to) in the direction you wish to toss the ender pearl to toss it. It does not work in Creative mode.
You right-click. However that is. If that doesn't seem to work, try checking your settings.
In survival, to break a minecart, all you have to do is right click a couple times on it. Do not hold the right mouse button down because it will not work.
