# How to Find APEX Built-in Substitution Strings



APEX has a set of built-in substitution strings which allow developers to reference things such as the current application ID, page number, date format, etc. _For more information about how to reference substitution strings read {% post_link variables-in-apex %}_.

Finding the list of built-in substitution strings can be a bit difficult for new users to APEX (thus this article). To get the complete list of built-in substitution strings:

- Got to [apex.oracle.com/shortcuts](https://apex.oracle.com/shortcuts)
  - Find your documentation for your version of APEX
- View the `Oracle Application Express App Builder User's Guide`
- Search Table of Contents for `Using Built-in Substitution Strings`

You'll find a complete list along with description and usage examples. If you're new to APEX or didn't know about all the substitution strings I suggest scanning through it so you know which ones are available and what they contain.
