load ssh keys with right-click menu or toolbar button

[heylix]

Summary

I'd really like an item in the right-click menu of an entry which allows me to add the key to the keyring, if there is one attached to the entry.

Context

I don't auto-add all of my keys but only select ones. The others have to be added through viewing an entry (doubleclick or right-click→edit or Ctrl+E) → SSH-agent → clicking "add to agent". (4 clicks)

Would be nice if we could reduce that flow to rightclick → add to ssh agent (2 clicks). Or have a tab at the bottom of the window to view the attached SSH agent files (2 clicks). Or even have a keyboard shortcut?

EDIT: I see this is already merged in #4290 and discussed in #2822. Only found this out after creating this issue, sorry!
