I am not familiar with your nice mouse  or its buttons, but here (in
stripped-down form) is the code I use to remap the double-click event:

Private Sub Auto_Open()
'Redefine the double-click event to call the DblClick sub.
Application.OnDoubleClick = "DblClick"
End Sub

Public Sub DblClick()
'New event logic for double-click.
MsgBox "Double-click code goes here", vbInformation, "DblClick"
End Sub

Private Sub Auto_Close()
'Restore the double-click key event to normal.
Application.OnDoubleClick = ""
End Sub

To make this work all the time, put the code in a module in your hidden
Personal.xls workbook.

Please note: some Excel add-ins, such as Hyperion SmartView for Office, may
contend with you for control of the double-click event, causing errors.

I guess I wasn't as clear as I could have
been about my issue. What my mouse  does is send  a keystroke
combination to the computer. So when I send a double-click, I really
send something like "Ctrl-I" twice in rapid succession. I would like
to write  a routine  that detects the time between clicks and either
interprets it as a single click  or a double  click.

I was thinking the routine could pause after the first "Ctrl-I" and
wait a specified interval for the next "Ctrl-I". But I'm not sure
what to wait for.

Any idea how I could do this?

Search for the topic "Time capture of less than one second" in this
group. I gave a Google groups link there, and Pascal also had a
solution.

This will enable you to monitor time in great detail.

To implement, start the code, waiting for the user to CTRL-I, start the
timer upon the first keystroke of "CTRL-I", and wait for x counts (x to
be defined by you). If after x counts, no second event, then reset
timer, and wait again. If second event within x counts, then execute
whatever code.

What I am unsure of is how to capture the keystroke (Don't know what the
code for CTRL-I is). Secondly how to limit the amount of processing
power this code will use, as it will continuously be monitoring stuff
from VBA. But only one way to find out.
