Can I spend from multiple wallets in Electrum (or somehow import/merge them)? Is it possible, in Electrum, to merge wallets, and or do a transfer using multiple wallet keys?  I have some dust in a wallet and would like to get it out. I'm hoping I can easily incorporate it into another payment.
Given the sum of the dust, this is primarily a curiosity. I know it's possible in the protocol, but wondering whether there's a high level way, or even a command-line way.
You could export the private keys from all the wallets you wish to send from, save them to a file. (Wallet-&gt;Private keys-&gt;Export (to .csv) , open in Excel and copy the private_key column to a new file)
Build a new wallet with imported private keys on Electrum (File-&gt;New/Restore-&gt;[+] Import Bitcoin Addresses or private keys)
The new wallet would contain all addresses you wish to spend from
