zsh: realized some things need to be functions

By that, I mean things that change my working directory need to be
functions

+# If I use this enough, I may make something that can do more
+# Ideas for what it could do in the future:
+# - somehow record typed commands so they can be automatically repeated like a macro
+#     - maybe get the length of the histfile before and after, executing the last X number of commands
+# - Maybe just add an argument that takes a command and executes it in all dirs
+# (although that wouldn't be as good as recording actions bc it's easy to do
+# that by just writing a for loop)
