Triuble with extrude

I’m a total newbie - I’ve been trying to extrude - it has worked for me before with no trouble but now insists on extruding along a diagonal line - Obviously I’ve done something - can anytell be how to fix this pleas?

After pressing E you’re not locked in. You can always right-click to cancel, but the region will still be copied, so you can then change views and just move with G. Also, while extruding, you’re not stuck. You can press any of the axis keys, rotate, etc.

To answer your question though, notice what color the axis is that it’s locking to… and press that key twice (red - locked to global X axis, press X once, now locked to local X axis, press X again, unlocked positioning.)

Thanks for that;)
