Change names of blades

[elvyre]

Hi everyone,
Thanks in advance for your help. Here is my problem: I would like to personalize the way multivectors are shown in Galgebra. This will be very helpful to work for me, because in some cases blades names like e1∧e2∧e3∧e4 are too heavy. For instance, one could want to work only with half the blades and show the others using dual blades. Alternatively, you may have some commuting blades, and this structure encourages you to use more convenient notations. Translating from Galgebra notation to your own ones is always a pain, and should not be done by hand... Does anyone see a way to do that? This is, in the end, a printing option: choose between several dictionaries of character chains for the blades. A crucial point is to handle the sign properly. For instance, one may choose -B2 for e1∧e3 to keep circular permutation (B1=e2∧e3 and B3=e1∧e2).
I hope this is not too difficult. Thanks!
