Feature request: Support key bindings to launch different shells/profiles

[kgfly]

Description

It would be very useful to support key bindings that can launch different shells from a shortcut.

For example, on Windows:

• Ctrl+Shift+1 → open a new tab/window running cmd.exe
• Ctrl+Shift+2 → open a new tab/window running WSL (wsl.exe)
• Ctrl+Shift+3 → open PowerShell

eg

{ key = "1", with = "control | shift", action = "Run", run = "cmd.exe" },
{ key = "2", with = "control | shift", action = "Run", run = "wsl.exe" },

Currently, Rio supports configuring a default shell, but key bindings cannot choose which shell/program is launched.

Current behavior

The shell is configured globally, for example:

[shell]
program = "wsl"
