Several buttons and fields lack mnemonics
Select "OpenSSH keys", choose a key, right-click on it and select "Properties". Press the
Alt key and keep it pressed.
Only "Change Passphrase" has a mnemonic. "Export" and "Delete SSH key" buttons both lack mnemonics. The "Name" field has no mnemonic either, so when I use the Tab key to circle through items there is no direct way to focus that text field.
