If for some reason you ever find yourself wanting to export your wallet keys from your local CLI install with axelard to Keplr wallet, you can do so as follows.
Find your account name.
./axelard keys list
Let's imagine for a moment that you find an address with the name mywallet.
Then you can export the private key in a format that can be directly imported into Keplr as follows:
./axelard keys export mywallet --unsafe --unarmored-hex
Beware, this is unencrypted and your raw numerical private key. If anyone gets a hold of this or sees this, assume they have complete control of your account. This is the nubmer you need to paste into the Keplr wallet "Import an existing wallet" screen.
