I have been taking advantage of the fact that the old ALT keyboard shortcuts from Excel '03 also work in '07, but have come across a very annoying problem: '07 requires a slight delay between pressing each key, while '03 allowed you to press them very fast.

Example: to paste values, you press ALT+E+S+V. In '03, I can press the entire key combination in well under a second. However, if I press that combination very quickly in '07, it pops up this little box that says:
Office 2003 access key: ALT, E,
Continue typing the Office 2003 menu
key sequence, or press Escape to cancel.

However, if I press ALT+E+S+V with a half second delay between each key stroke, it works fine. Strangely, if you use a command with fewer keystrokes (for instance, inserting a cell/row/column, which is ALT+I+E) it works just fine at any speed.

So, my question is how do I get '07 to allow me to do the more full commands like ALT+E+S+V at full speed?
