You should read through the documentation for MPLAB or MPASM.  They detail
the instruction set for PIC assembly.  Also, the datasheets for most of the
PICs available have instruction set summaries at the end.

But for now, you can use "MOVF Register_To_Move, W" or if you're using
MPASM, you can also use the mnemonic "MOVFW Register_To_Move".
