Example `buffer_actions.lua`

--[[--
Example on various ways to make the buffer interactive, i.e. responding to user
input. This example illustrates the use of implicit and explicit hotspots using
either function or table commands, as well as key commands and responding
directly to key presses.

For the purpose of this example the `F6' key will be set to show the
example buffer. Provided that TextUI is installed, you can copy this to
your .textadept/init.lua, and press `F6` to try it out.
