How I tested this

Tab navigation between sections

• Press Tab to switch focus between:
  • Local tab → Servers tab
  • Servers tab → Local tab

Servers tab behavior

• Connect to a server in Servers tab
• Verify keyboard navigation:
  • Press J to move focus from the server tree → cron table
  • Press J again to move focus from cron table → server tree
• Press Tab to move focus out of the Servers tab (to Local tab)

Hi @bcExpt1123

Thank you for this PR!

I am now testing it a bit, but I do not find how to use the jump feature you are talking about. Could you please provide a bit more details about how to use it?

What I see is that with tab you can change the tab and with jkhl you move withing the current tab. What J does?

Thanks!

Hi @antoniorodr
Thanks for reviewing my PR.

We can use Tab to switch between the Local and Servers tabs. However, within the Servers tab, we also need a way to move focus between the left server tree and the main content (the cron table).

Since Tab is already used for switching tabs, it can’t be reused for this interaction. The jkhl keys are also not suitable for this purpose.

As discussed in issue #36, we need a dedicated key for this action (similar to a “jump” behavior). To address this, I introduced a new shortcut: Shift + j.(J means Shift+j)

When pressed within the Servers tab, Shift + j toggles focus between:

• the server tree (left panel), and
• the cron table (main content)

This serves as an alternative to Tab for intra-tab focus switching, while keeping Tab reserved for switching between tabs.

Thanks for the explanation!

Of course, I did not try to move focus to the main content withing the servers tab, I am sorry.

I will continue reviewing the code. I will come back to you if I have any questions.

Thanks!
