The Always On key map (or "Control" for old WoW configs) has "Activate Mouse Repeat" with no default Hotkey. You can configure that. This has been the recommended place to set it for a long time...
If you don't have that:
1. use the Mapped Key Wizard (e.g. from the Wizards menu)
2. it will first have you pick a Key Map to put your toggle in (a Key Map that is assigned to your Character Set....)
3. on the next page tell it to configure a "Broadcasting Toggler"
4. the options on the last page will help you configure a toggle for BOTH keyboard AND mouse. steps 5-10 tell you how to change it to only toggle mouse.
5. in the top left pane, select the Key Map you added it to
6. In the bottom left pane, expand your Mapped Key to see Steps 1 and 2
7. Select step 1
8. In the bottom right pane find and select the Action that says "repeater mouse On keyboard On"
9. Un-check the Key repeat box, and it will no longer affect Keyboard, just the mouse
10. Repeat steps 7-9 for Step 2 except it says Off instead of On.
