I read many Emacs blogs since I started the trip of learning it. There are great beginner's tutorials and also webpages for more advanced users. However, there's a habit I find repeatedly on the majority of sites which goes against one of the Almighty Editor advantages: instructions usually refer to default keybindings, like it was invariant that you visit files only with C-x C-f, or like the only admited shortcuts to the beginning and ending of the current line where C-a and C-e, or if the incremental search inevitable required to type C-s. In my case, keybindings for all these functions and many others are personalized, and the default ones are disabled (I visit files with C-o, move the point to the beginning or end of the line with M-h and S-M-h, and activate incremental searches with C-f).

My advice to all the Emacs educator's community is to refer and cite the suggested function names in tutorials and comments, instead of using their default keybindings. For example, you should talk about isearch-forward instead of writing C-s; it is better to write the whole move-beginning-of-line function name instead of only refering to C-a. This way, it is possible to follow step by step instructions using execute-extended-command (generally executed with M-x, although in my setup that happens with M-a).

Then, if you need to know the keybinding to a function, just execute describe-function to get its abstract and see its keybindings.
