vs2008 mystery: Quick macro record and playback shortcuts not allowed?

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 开发者_如何学编程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?

Snagit 9.1.3 was the culprit.
Snagit is a really useful time saving screen capture tool from Techsmith.

Ctrl+Shift+P ~~ I changed this to Print Screen.
Ctrl+Shift+R ~~ repeat last capture is now Ctrl+Shift+Alt+0.

While I was at it, I changed this too:
Ctrl+Shift+X ~~ hide Snagit window toggle is now Ctrl+Shift+Alt+9.

vs2008 has so many keyboard shortcuts predefined that it
is easy for some other software to steal one of them.

For anyone who needs to frequently capture and annotate screen images,
Snagit will quickly repay its purchase cost in time saved.
