+# ISE Compatibility
+
+While the PowerShell extension for VSCode does not seek
+complete feature parity with the PowerShell ISE,
+there are features in place to make the VSCode experience more natural
+for users of the ISE.
+
+This document tries to list settings you can configure in VSCode
+to make the user experience a bit more familiar compared to the ISE.
+
+## Key bindings
+
+| Function                              | ISE Binding                  | VSCode Binding                              |
+| ----------------                      | -----------                  | --------------                              |
+| Interrupt and break debugger          | <kbd>Ctrl</kbd>+<kbd>B</kbd> | <kbd>F6</kbd>                               |
+| Execute current line/highlighted text | <kbd>F8</kbd>                | <kbd>F8</kbd>                               |
+| List available snippets               |                              | <kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>J</kbd> |
+
+## Tab completion
+
+To enable more ISE-like tab completion, add this setting:
+
+```json
+"editor.tabCompletion": "on"
+```
+
+This is a setting added directly to VSCode (rather than in the extension),
+so its behavior is determined by VSCode directly and cannot be changed by the extension.
+
+## No focus on console when executing
+
+To keep the focus in the editor when you execute with <kbd>F8</kbd>:
+
+```json
+"powershell.integratedConsole.focusConsoleOnExecute": false
+```
+
+The default is `true` for accessibility purposes.
+
+## Do not start integrated console on startup
+
+To stop the integrated console on startup, set:
+
+```json
+"powershell.integratedConsole.showOnStartup": false
+```
+
+**Note:** The background PowerShell process will still start,
+since that provides intellisense, script analysis, symbol navigation, etc.
+But the console will not be shown.
+
+## Assume files are PowerShell by default
+
+To make new/untitled files register as PowerShell by default:
+
+```json
+"files.defaultLanguage": "powershell"
+```
+
+## Color scheme
+
+There are a number of ISE themes available for VSCode
+to make the editor look much more like the ISE.
+
+In the [Command Palette]
+type `theme` to get `Preferences: Color Theme` and press <kbd>Enter</kbd>.
+In the drop down list, select `PowerShell ISE`.
+
+You can set this in the settings with:
+
+```json
+"workbench.colorTheme": "PowerShell ISE"
+```
+
+## Show-Command
+
+Thanks to the work of [@corbob](https://github.com/corbob),
+the PowerShell extension has its own command explorer.
+
+In the [Command Palette]
+enter `PowerShell Command Explorer` and press <kbd>Enter</kbd>.
+
+## Open in the ISE
+
+If, after everything, you want to open a file in the ISE,
+you can use <kbd>Shift</kbd>+<kbd>Alt</kbd>+<kbd>P</kbd>.

+## VSCode is not working like the ISE
+
+The PowerShell extension does not aim to perfectly recreate
+the experience of the PowerShell ISE.
+However, we do want to support compatibility whenever possible
+to do so without breaking existing functionality.

+Please also see [the ISE compatibility doc](./ise_compatibility.md)

 ## Known Issues in the Extension
