Regular reader Phil offers some help on help<\/a> in the comments to the vc-annotate<\/a> post. The first suggestion is something I think he’s mentioned before but that I promptly forgot. I often want to look at the source code that implements an Emacs command. Sometimes it’s just curiosity, other times I want to extend or modify the command or implement something similar. My normal procedure for this is to bring up the help page for the command with \u3010Ctrl<\/kbd>+h<\/kbd> f<\/kbd>\u3011 and then click on the link to the source code. Actually, there’s a function that does that for you: find-function<\/code>. Phil assigns the key sequence \u3010Ctrl<\/kbd>+h<\/kbd> Ctrl<\/kbd>+f<\/kbd>\u3011 for this. I do this operation often enough that this is a real time saver for me and I’ve added it to my init.el<\/code>.<\/p>\n

The second two commands are built in but virtually unknown. The sequence \u3010Ctrl<\/kbd>+h<\/kbd> F<\/kbd>\u3011 is just like \u3010Ctrl<\/kbd>+h<\/kbd> f<\/kbd>\u3011 except that it brings up the info page for the command. Similarly \u3010Ctrl<\/kbd>+h<\/kbd> K<\/kbd>\u3011 brings up the info page given the key sequence for the command.<\/p>\n

These are really useful things to know so we all owe Phil thanks for (once again) pointing them out. Maybe now that I’ve blogged about them I’ll actually remember them.<\/p>\n","protected":false},"excerpt":{"rendered":"
