UX - Change keypair dialog not usable without mouse

[Soleone]

This is a smaller polish issue, but one of these things that ensures the app comes across as native and solid as possible:

1. When opening the "Change Keypair Name" dialog the textfield for entering the new name is not focussed, the user can't start typing immediately.

2. The old/default name is not displayed, so can't be edited. It just shows a blank textfield.

3. Can't press Enter to confirm the new name (or even use Tab to change elements as workaround), have to use the mouse to click Okay.
