 | cTIME            |      v2       | `cTIME <TIMESTAMP>`                 | Converts a Millisecond-Unix-Timestamp to human-readable time, ready to output. |
 | MAKEANIMATION    |      v1       | `MAKEANIMATION <Type> <Sub> [WORD]` | Outputs a valid animation value for the `ANIMATION` command. <br /><br />Types: <br />`Rotate`:<br />`0   -  / - \ \|`<br />`1   -  ^ > V <`<br />`2   -  + x`<br />`3   -  p d b q`<br />`Range`:<br />Returns a set of numbers from 0 to the given number.<br />`Alphabet`:<br />Returns **n** letters of the alphabet. Maximum is 26.<br />`Appear`<br />Accepts the **WORD** Parameter, while a *0* for **Sub** is required. It makes the given word appear one letter at a time. |
 | PRINT            |      v1       | `PRINT <String>`                    | Prints the **String**. Only difference to the built-in `echo` is that no newline is added at the end. |
+| READKEY | v3 | `READKEY <MS>` | Waits **MS** Milliseconds for a keypress, then returns 0. The returned number when a key is pressed consists of two values:<br />Example: `7068`<br />The *68* stands for the <u>KeyCode</u> of the pressed key, in this case *D*. The 7 at the beginning stands for the Modifier-buttons that were pressed:<br />`0 - None, 1 - Alt, 2 - Shift, 3 - Alt+Shift, 4 - Control, 5 - Control+Alt, 6 - Control+Shift, 7 - Control+Alt+Shift`.<br />These values can be extracted using *Division* and *Modulo*. |
+| SLEEP | v3 | `SLEEP <MS>` | Pauses the script for **MS** Milliseconds. |
+| STARTINVISBLE | v3 | `STARTINVISIBLE <script file>` | When used with `START /B`, this starts a batch-script as invisible. This script can then do whatever you want. When executed, the command writes the PID of the started process to `%temp%\processid.txt`, so you can terminate it with `taskkill` at any time. This may be updated to return the PID in *errorlevel* and not require *start /b* in a future version. |
 | STRLEN           |      v1       | `STRLEN <String>`                   | Returns the amount of characters in **String** in `%errorlevel%` |
 | uTIME            |      v2       | `uTIME`<br />`uTIME -c`             | Returns the current time as Millisecond-Unix-Timestamp. |
 |                  |               | `uTIME -f <File>`                   | Returns the last modification date for **File** as Millisecond-Unix-Timestamp. |
