List of SAP Transaction Codes

When I started to work with SAP I got really mad about all these non-sensical 4 digit SAP transactions. Of course, there are many useful lists on the web, but, for one reason or the other, I could not find one overview, which suits my own needs. So, in a "Slow And Painful" (= SAP?) process, I created my own Cheat Sheet (for consultants, developers, users), including the most important SAP transaction codes (functional and technical). It covers SAP-FI (banks, payments methods, chart of accounts, posting periods) Workflow, Transports, Spool, SAP Standard Reports, Jobs and Events, Archive Link, User Administration, Workflow, Batch Input, ABAP, the Data Dictionary, and some other SAP basis items. Some examples which are included in the PDF:

Please be invited to use this list and/or leave some suggestions for enhancement (see "Disclaimer" for contact information). However, out of experience, allow me to make one stipulation: although this cheat sheet is freely available, please refrain from uploading it to other servers.

The items are categorized: ABAP, Data Dictionary, FI (Accounting, General Ledger), CO (Controlling), Spool, Archive Development Kit (ADK), BAdI, runtime, transport management, authorization, translation, logs etc.).

Below is a screenshot of the pdf, to show an overview of the structure (the list contains both customizing and operational transaction codes):
