An other way would be simply to use TM's Find Function. Look for  
regexp [0-9A-z]+. Use the APPLE+G for jumping forwards, and SHIFT 
+APPLE+G for jumping backwards (this only works partly; sometimes you  
have to press SHIFT+APPLE+G several times).

With that regexp you can create your own macros easily.
