Using .[ and .] in a macro

[hbezemer--- via]

Dear all,I would like to create a macro along the lines of:.de 
CITE.[\\$2\\$1.]\\$3..Which would result in:.CITE <mykeyword> <optional left of 
label stuff> <optional right of label stuff>The problem that arises is that 
refer sees the definition of the macro asa citation (of course).Is there an 
elegant way to get this to work?Kind regards,Hans
