* Check if there is *a lot of* RAM! Either upgrade it or continue:

* If not, then there are a lot of hard disk read/write accesses. Check the hard disk for bad sectors (SeaTools, chkdsk c: /p). Attention: this may need your Windows XP install disk afterwards, but can increase the speed a lot!

* Also each read/write-access on the hard drive may provoke the anti virus software to check each moved data for malware before every access. Then, additionally it may access the hard disk for virus signature information. Check for the CPU-Usage and Page faults of your AV-Software (via taskmgr) and disable some less needed features of it.

* A large delay when right-clicking something might be caused by a cluttered registry. Use RegCleaner 4.3's auto-clean to remove the useless entries.

* Also defrag your hard disk to improve perfomance (a bit). I use MyDefrag (opensource, easy-to-use, needs no configuration, defaults make a lot of sense)

I like XKCD showing problems.

A,C,D

= add, change, delete to the end of the line. I often saw me doing things like c$ to do the same as C does.

xp

= switch two chars (actually remove + paste 1 char) I often did things like 2s instead.

Ctrl+I, Ctrl+O

= browse forward and back in position history. I often "scrolled" with j,k only.

Use folding

With the useful option.

set foldmethod=intend

and zM, zo, zC, zr etc. you can get a fast overview of your classes in Python.

Finally the dot, to repeat the latest replacing, etc. at another position
