Answer 4

Typing / on any file dialog will give you a "go to folder" dialog, which autocompletes with tab (you have to wait a second for it to work). This lets you type in the full path, from the root / folder.

Extra handy if you want to open from / save to hidden locations or already have the command line path you want to save something in.

This can be also accessed via ~ (i.e. the tilde key, to start from your home directory, e.g. ~/Documents) or using cmd+shift+G (which starts with the most recently entered directory).

Answer 30

Here's a great one (for switchers) I got from the TextMate blog;

Create the folder ~/Library/KeyBindings (if it doesn't already exist) In there, create a key-binding file DefaultKeyBinding.dict In that file, put this text (including all braces & punctuation);

{
    /* home */
    "\UF729"  = "moveToBeginningOfLine:";
    "$\UF729" = "moveToBeginningOfLineAndModifySelection:";

    /* end */
    "\UF72B"  = "moveToEndOfLine:";
    "$\UF72B" = "moveToEndOfLineAndModifySelection:";

    /* page up/down */
    "\UF72C"  = "pageUp:";
    "\UF72D"  = "pageDown:";
}

Save the file, and when you next start a Cocoa app (eg Mail, TextEdit etc) you will find that Home, End, Pg Up and Pg Down now work as they do on Windows.

It's well worth having a look at the whole of that article - he explains exactly how to make this file and how the bindings work, with information about the other keycodes etc.
