in vs2008, Tools, Macros,
Record TemporaryMacro keyboard shortcut toggle is Ctrl+Shift+R;
Run TemporaryMacro keyboard shorcut is Ctrl+Shift+P for playback.

I've used them before, but they've stopped working.

If I open Tools, Options, Keyboard, then navigate to a command like Tools.Run that has no assigned keyboard shortcut, I can experiment by pretending to assign a keyboard shorcut: I simply click inside the "Press shortcut keys:" textbox and try different keystroke combinations.

Examples:
Ctrl+p: currently assigned to File.Print
Ctrl+r: currently assigned to various uses
Ctrl+Shift+Q: available
Ctrl+Shift+B: currently assigned to Build.BuildSolution
BUT
vs2008 will not even allow me to type either of
Ctrl+Shift+P or Ctrl+Shift+R in the "Press shortcut keys:" textbox.
When I type those combinations, nothing appears in the "Press shortcut keys:" textbox.

Please note: I can record and playback a temporary macro by using the menu commands, however, the mouse is like a turtle when compared to the keyboard.

Any ideas why this very useful vs2008 feature is broken?

Thank you.
