Yes. On the Commodore PET the BASIC keywords were stored in a lookup table 
using this technique, and since shifted letters had the high bit set, you 
could abbreviate keywords by shifting:

fO i=1 to 100 sT 5: ? i: nE

(Didn't save anything but typing time: they were stored as one-byte tokens 
anyway AFAIR).
