[FEATURE] lazygit alike navigation and usage

[jorgheymans]

I like this tool a lot, it has really great potential as an alternative to bloated database browsers. Oracle support is a bit early days still, but i'm sure it'll improve !

One thing i struggled with though is intuitive navigation between panels. Just using tab should cycle through all the panels, shift-tab for reverse. Pressing question mark in a tab to see the possible shortcut keys etc. I guess i'm spoiled by lazygit which does this extremely well, it's something to learn from I think rather than introducing new keybindings.
