Remap “Home” and “End” to beginning and end of line

The default shortcuts for moving to beginning or end of (wrapped) lines are  and  and  or A and E move to the beginning or end of unwrapped lines (or paragraphs).  and  move backwards/forward by words, and all of these are compatible with holding Shift to select during the corresponding moves.
You could remap home and end by creating ~/Library/KeyBindings/ and saving a property list like this as DefaultKeyBinding.dict:
{
    "\UF729"  = moveToBeginningOfLine:; // home
    "\UF72B"  = moveToEndOfLine:; // end
    "$\UF729" = moveToBeginningOfLineAndModifySelection:; // shift-home
    "$\UF72B" = moveToEndOfLineAndModifySelection:; // shift-end
}
Most of the keybindings for editing text in OS X are defined in /System/Library/Frameworks/AppKit.framework/Resources/StandardKeyBinding.dict.
Applying changes requires reopening applications. DefaultKeyBinding.dict is ignored by some old versions of Xcode (works with latest version 6.3.1), Terminal, and many cross-platform applications.
See Cocoa Text System and my website for more information about the customizable keybindings.
Terminal's keybindings can be customized in Preferences > Settings > Keyboard. \033OH moves to the beginning of a line and \033OF to the end of a line.
In Eclipse, key bindings should be modified in Preferences > General > Keys. You need to modify default bindings for commands Line Start and Line End (replace ⌘← by ↖ and ⌘→ by ↘). For selection to work, also modify Select Line Start and Select Line End.
PS: You may need to logout and login again for the ~/Library/KeyBindings/DefaultKeyBinding.dict change to take effect.
