`Ctrl+Shift+S`	Save As
`Ctrl+Z`	Undo
`Ctrl+Shift+Z` or `Ctrl+Y`	Redo

`Ctrl+P`	Quick Open
`Ctrl+Shift+M`	Toggle Problems panel
Ctrl+`	Toggle integrated terminal
`Ctrl+W`	Close current editor tab
`Ctrl+=`	Zoom in
`Ctrl+-`	Zoom out
`Ctrl+0`	Reset zoom
`Delete`	Delete selected widget (when a widget is selected in the GUI editor preview)

Note: On macOS, replace Ctrl with Cmd (⌘).

Debug Configuration

Running a Apleno Designer app uses VSCode's built-in Debug infrastructure. The launch.json created by Create new project contains:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "apleno",
      "request": "launch",
      "name": "Apleno preview"
    }
  ]
}

You can also trigger this configuration by pressing F5 in VSCode when you have the pgm debug type active.

Runtime Configuration File

.vscode/apleno.json stores the paths to your R/Python/Conda interpreters:

{
  "r": {
    "path": "C:/Program Files/R/R-4.3.0/bin/R.exe"
  },
  "python": {
    "path": "C:/Python311/python.exe"
  },
  "conda": {
    "path": "C:/Users/user/miniconda3/Scripts/conda.exe"
  }
}

You do not need to edit this file manually. Use the Apleno: Choose ... path for preview commands instead.
