Allow individual keys to be edited

[PooperPig]

Is your feature request related to a problem? Please describe.
I have a macro with a long series of keypresses. I realise the 2nd one is wrong. I entered 'X' and I meant 'C' (for example). I can't change it - so I have to remove everything and start again!

Describe the solution you'd like
When a key is selected in the list, selecting an element should overwrite the current key

Describe alternatives or workarounds you've considered
Being able to insert an element in the list would make the change faster, though not ideal. i.e. you could delete thej incorrect key and insert the correct one.

Additional context
e.g. I add my email address [email protected] to a macro, but I simply mis-enter the 'e' from email - it should be possible to just change it.
