Assume I hold Bitcoins on multiple addresses managed by my local Electrum wallet.
Simplified example with shortened addresses:

address:        amount:
556677         0.0000410
334422         0.0000500
229977         0.0000700

Now I want to send an amount of 0.0000600 Bitcoin (plus fees) to someone else.

How do I tell Electrum from which of my addresses the amount (resp.how much) should be taken?

How do I tell Eletrum from which of my addresses the (currently unknown) fees should be taken?

The "send" tab does not provide a "take xxx from local address" entry field (resp.fields)

How does this work?
