The "Breakpoints" window is used to display all breakpoints currently set in the different units in LuaEdit. Useful information is beeing displayed in this window such as the file name and line number where the breakpoint is defined, its status, etc.

You can set a condition on a breakpoint. In runtime, the condition will be evaluate just before breaking. If the condition returns "true", it will break. Otherwise it will ignore the breakpoint and persue its execution. For example, as you can see in the image below, the variable x must equal to 10 in order for LuaEdit to stop on the breakpoint defined at line 31.
