Tab navigation shortcuts

[jonas-grgt]

Today to navigate the top tabs you need to press het <meta-key> + number combination.
In most terminals this must be enabled and will map to alt.

This isn't intuitive and although it is mentioned in the README I've received the feedback that people are stuck.

Therefor I would like to open a discussion on an alternative default shortcut combination to navigate the tabs.

Alternatives I could think of:

• ctrl + number won't work as the terminal doesn't send the ctrl signal only the number -> ctrl+<number> not captured charmbracelet/bubbletea#1207
• number only, i.e 1 to move to tab 1, 2 to move to tab 2 etc .. -> this is the most problematic to implement as numbers might also be used by other components such as text input fields.
• ctrl + char for example ctrl + g to move to the consumer groups tab
• keep it as it is, meta-key + number is just fine
