Summary
The codebase already maintains a _navigation_history breadcrumb cache (50-entry FIFO) in panel.py, but there's no key binding to navigate back/forward through previously visited directories.
Motivation
This is a low-effort, high-value addition. The infrastructure exists — we just need to expose it via keybindings. Users navigating deep directory trees frequently need to "go back" to where they were, without manually retracing steps through ...
Midnight Commander supports this pattern, and modern file managers (Nautilus, Dolphin, Finder) all have back/forward navigation.
Proposed Key Bindings
| Key |
Action |
Alt+Left |
Go back to previous directory |
Alt+Right |
Go forward (after going back) |
Implementation Notes
panel._navigation_history already stores parent→child breadcrumbs (dict, 50-entry limit)- Need to add a proper back/forward stack (separate from breadcrumb cache)
- Back stack: push current dir before navigating, pop on Alt+Left
- Forward stack: push current dir when going back, pop on Alt+Right; clear on manual navigation
- Consider showing history in a dropdown (future enhancement)
