• Activate multi line editing with Alt key
• Using _ as a thousand separator. For example: number : INT := 1_000_000
• (TwinCAT 4024+) Ctrl + K, Ctrl + C to comment on or more lines and Ctrl + K, Ctrl + U to uncomment them.
• In a CASE statement you can use multiple cases like 1, 3, 61 or a whole range like 1..10.
• Implicit enums: colors : (Red, Blue, Green); https://alltwincat.com/2021/11/16/local-enumerations/

• Return an boolean immediately:

  
  // Do not do this
  METHOD largerThenTwelve
  VAR_INPUT
      number : INT;
  END_VAR
  
  IF number > 12 THEN
      largerThenTwelve := TRUE;
  ELSE
      largerThenTwelve := FALSE;
  END_IF
  
  // Do this
  METHOD largerThenTwelve
  VAR_INPUT
      number : INT;
  END_VAR
  
  largerThenTwelve := number > 12;

- Use `{attribute 'call_after_init'}` to call a method once after some  _after_ the function block has  been initialized instead of using `bInitialize`. 
- Reduce the use of REFERENCE and POINTER as much as possible
- Do not call methods from multiple tasks. If you do use [this](https://infosys.beckhoff.com/content/1033/tc3_plc_intro/45844579955484184843.html?id=2972649925198044529).
