SAP Hotkey : Searching for dot "." character

Hi,

I would like to do a search a string including the dot "." sign directly from a field.

Example :

VA01 : Material field

If i input "=AB.CD" then press F4, "AB" is feeded into first field of search help and "CD" into second field.

What if i want to search "AB.CD" into first field ?

I tried different escape character (including # that should interpret next character literaly (Wildcard Characters - BC - SAP Style Guide - SAP Library)

but none did work (\ / " ').

The only workaround that i have found yet is to input "+" instead of "." but then the wildcard character "*" is not automatically added so i have to input

"=AB+CD*", that is not 100% satisfying, because "+" could be any character not only "."

Thanks for your help !

PS : Using SAP GUI 7.40 for windows.
