make ctrl-A functional in key selection dialog

i participate in an encrypted mailing list pgpnet@yahoogroups.com. the group now has 32 members and each message must be encrypted to every member's public key. what i now do when using firegpg is to hold down ctrl and click all 32 keys one after the other. many applications allow highlighting everything using ctrl-A. i would like that option in firegpg.

i have a group=pgpnet line in gpg.conf to use when encrypting from the c/l but firegpg does not pick that up when presenting the key selection dialog. my guess is that the ctrl-A solution would be a simpler although less elegant way to make at least my life easier :-)
