Inserting a Public Key Block ============================ The function `mc-insert-public-key' will extract a key from your public keyring and insert it into the current buffer. `mc-write-mode' binds this function to `C-c / x' by default. This function is useful for sending your public key to someone else or for uploading it to the key servers (see Key Servers.). The inserted key will be the first one on your public key ring which matches the string `mc-pgp-user-id' (see Encrypting a Message: Encrypting.). You may want to insert a different public key instead; for example, you may have signed someone's key and want to send it back to them. To do so, pass a prefix argument to `mc-insert-public-key'. (That is, type `C-u C-c / x'.) You will be prompted for a string; the first key on your public key ring which matches that string will be inserted.
