+# FOP Macros
+
+Collection of macros to to help during the FOP exam.
+If any macro breaks your typing,
+press and release `ctrl + shift + alt` to fix those keys.
+
+## Getting started
+
+1. Install [sxhkd](https://wiki.archlinux.org/index.php/Sxhkd)
+and [xdotool](https://wiki.archlinux.org/index.php/Xdotool#Automation).
+
+1. Run `sxhkd -c macros.sxhkd` in the background.
+
+## Macros
+
+### aspekts of oop
+`ctrl + shift + alt + a`:
+[Four buzz words](https://www.indeed.com/career-advice/career-development/what-is-object-oriented-programming)
+professors love to hear.
+
+### filter map
+`ctrl + shift + alt + f + m`:
+Racket implementation of
+[filter map](https://docs.racket-lang.org/reference/pairs.html?q=map#%28def._%28%28lib._racket%2Flist..rkt%29._filter-map%29%29).
+You might need to inline `f` (the mapper) and `p` (the predicate).
+Remove `f` to get `filter` or `p` to get `map`.
+
+### interface
+`ctrl + shift + alt + i`:
+Standard [java interface](https://www.w3schools.com/java/java_interface.asp)
+with five [methods](https://www.w3schools.com/java/java_methods.asp).
+
+### class
+`ctrl + shift + alt + c`:
+Standard [java class](https://www.w3schools.com/java/java_classes.asp)
+with a lot of boilerplate.
+
+### exception
+`ctrl + shift + alt + e`:
+Standard [java exception](https://www.tutorialspoint.com/java/java_exceptions.htm)
+with a costume [constructor](https://www.w3schools.com/java/java_constructors.asp).
+
+### listitemmethod
+`ctrl + shift + alt + l`:
+A Method to work with two `ListItem<T>` "pointers" without recursion.
