- [Lua Basics](https://luadoc.edgetx.org/edgetx_2.5/part_ii_-_opentx_lua_api_programming_guide/lua-basics.md): Lua is a small but powerful language. This section will explain a few of the most important concepts.
- [Loading Code Modules Dynamically](https://luadoc.edgetx.org/edgetx_2.5/part_ii_-_opentx_lua_api_programming_guide/loading-code-modules-dynamically.md): Lua makes it easy to load and unload code modules on the fly, to save memory or to provide program extensions.
- [Saving Memory](https://luadoc.edgetx.org/edgetx_2.5/part_ii_-_opentx_lua_api_programming_guide/saving-memory.md): This chapter will show you some ways that large script projects can be fitted into the limited memory of our radios.
- [Using Key and Touch Events](https://luadoc.edgetx.org/edgetx_2.5/part_ii_-_opentx_lua_api_programming_guide/using-key-and-touch-events.md): This section will discuss how interactive scripts receiving user inputs via key and touch events can be created.
- [Drawing Flags and Colors](https://luadoc.edgetx.org/edgetx_2.5/part_ii_-_opentx_lua_api_programming_guide/drawing-flags-and-colors.md): This section will give some technical details for radios with a color screen.

- [Constants](https://luadoc.edgetx.org/edgetx_2.5/part_iii_-_opentx_lua_api_reference/constants.md): This section describes various constants that are provided for Lua by EdgeTX.
- [Key Event Constants](https://luadoc.edgetx.org/edgetx_2.5/part_iii_-_opentx_lua_api_reference/constants/key_events.md): This page describes the value that is passed to scripts in the event parameter. It is used in Telemetry and One-Time scripts, as well as widget scripts in full screen mode.
- [Touch Event Constants](https://luadoc.edgetx.org/edgetx_2.5/part_iii_-_opentx_lua_api_reference/constants/touch-event-constants.md): In addition to the key events described in the previous section, radios with a color touch screen also provide touch events to the widget scripts.
- [Flags and Pattern Constants](https://luadoc.edgetx.org/edgetx_2.5/part_iii_-_opentx_lua_api_reference/constants/flags-and-pattern-constants.md): Many of the lcd functions accept parameters named flags and patterns. The names and their meanings are described below.
- [Color Constants](https://luadoc.edgetx.org/edgetx_2.5/part_iii_-_opentx_lua_api_reference/constants/color-constants.md): On radios with color display, a color may be added to the flags described above.
