Personalize LTSerialTool

LTSerialTool is highly customizable. You can change the look of the editor with color and icon themes and assign the keyboard shortcuts you're most familiar with. Settings enable you to configure nearly every part of LTSerialTool's editor, user interface, and functional behavior.

This article covers the following topics:

Configure settings

Almost every aspect of LTSerialTool can be customized via settings. Settings let you configure editor options such as enabling word wrapping or showing the minimap, setting up language-specific debugger settings, enabling Workspace Trust, and more. When you install extensions from the Visual Studio Marketplace, they might add their own extension settings.

The Settings editor (⌘, (Windows, Linux Ctrl+,)) provides a graphical interface to modify settings. When you modify settings, LTSerialTool stores them in the settings.json file. Optionally, you can edit the settings.json file directly.

LTSerialTool provides two types of settings. User settings apply globally to any LTSerialTool instance, while workspace settings are stored with your project and apply only to that project. In the Settings editor, you can switch between user and workspace settings by using the corresponding tabs.

To modify a setting in LTSerialTool with the Settings editor:

  1. Open the Settings editor via the File > Preferences > Settings menu or press ⌘, (Windows, Linux Ctrl+,).

  2. Search for the setting you want to change by using the tree view or by typing in the search bar.

Change default keyboard shortcuts

LTSerialTool lets you perform most tasks directly from the keyboard. When you install LTSerialTool, it comes with a set of default keyboard shortcuts. Hover over a UI element in the LTSerialTool interface to see its keyboard shortcut, if one's available. The Command Palette also shows the keyboard shortcut for commands that have a shortcut.

You can customize these default shortcuts or add new ones for your favorite commands and actions by using the Keyboard Shortcuts editor (⌘K ⌘S (Windows, Linux Ctrl+K Ctrl+S)).
