70 Things I wish I knew when I started using Macaulay2

1. I wish I had known about autocomplete feature in emacs sooner (M=meta): M -/
2. I can use sub (substitute) to change the ring my polynomials live in
3. peek [object], will give you the internal details of an object
4. code methods [function], will show you the Macaulay2 code behind most functions and where you can find the code
5. ``viewHelp x" brings up the HTML documentation for function/object/etc x.
6. peek'_n will peek n levels deep
7. make check checks everything and should be run before any pull request.
8. toExternalString P gives me a string constructing P
9. That you can use " list / function " to apply a function to all the elements in a list.
10. Use last baseName to get the index of a subscripted variable, e.g. last baseName x_{2,3} is {2, 3}.
11. That the command "restart" resets a session.
