🚀 Why R-Shell?

Most SSH clients (FinalShell, MobaXterm, Xshell) run on Java or Electron — burning memory even at idle. R-Shell uses Rust + Tauri 2 for native performance at a fraction of the cost.

Memory Comparison

Measured on macOS (Apple Silicon, 16 GB RAM) using footprint:

App	Technology	Memory	Relative
R-Shell	Rust + Tauri 2	~34 MB	1×
FinalShell	Java	~1.7 GB	~50×

Installer Size

Platform	R-Shell	FinalShell	Savings
Windows	3.99 MB	64 MB	16× smaller
macOS	8.13 MB	102 MB	12× smaller

No bundled JVM or Chromium — Tauri uses the OS native webview.

🎯 About

R-Shell combines an interactive terminal, dual-panel file manager, remote desktop viewer (RDP/VNC), real-time system/GPU monitoring, and log viewing in a single VS Code-like workspace. Built with Rust for native performance and minimal resource usage.

• Native Performance — Tauri 2 + Rust backend, not Electron or Java
• Cross-Platform — macOS, Windows, and Linux
• Multilingual UI — English, Simplified Chinese and Polish, with more languages welcome

⌨️ Keyboard Shortcuts

Shortcut	Action
Ctrl+B	Toggle Connection Manager
Ctrl+J	Toggle File Browser
Ctrl+M	Toggle Monitor Panel
Ctrl+Z	Toggle Zen Mode
Ctrl+\	Split terminal right
Ctrl+Shift+\	Split terminal down
Ctrl+1 – Ctrl+9	Focus terminal group
Ctrl+W	Close active tab
Ctrl+Tab / Ctrl+Shift+Tab	Next / previous tab
Ctrl+A, D	Detach session to background (Xshell-style)
Cmd/Ctrl+V	Paste into terminal
Cmd/Ctrl+F	Search in terminal
F3 / Shift+F3	Find next / previous

Layout shortcuts are registered at the OS level but ignored while terminal input is focused, so terminal-native bindings (e.g. tmux Ctrl+B) still reach the shell.
