Disclaimer: The details of this post are shamelessly ripped from phatness.com. All credit to those guys, I just wanted a copy for myself for future reference.
On every OS ever, Home, End, Pg Up and Pg Down keys work like so:
- Home -> move the cursor to the beginning of the line - End -> move the cursor to the end of the line - Pg-Up -> move the cursor up the length of the viewport - Pg-Dn -> move the cursor down the length of the viewport |
But OSX in all its infinate wisdom decided that doesn’t make sense. Instead they should work like so:
- Home -> move (nothing, not even the cursor, just your view) to the beginning of the DOCUMENT - End -> move (nothing, not even the cursor, just your view) to the end of the DOCUMENT - Pg-Up -> move (nothing, not even the cursor, just your view) up the length of the viewport - Pg-Dn -> move (nothing, not even the cursor, just your view) down the length of the viewport |
Now I’m not one to criticise… but that’s stupid and anyone who likes it is stupid 
How to Fix
There’s a really useful open source utility out there called DoubleCommand which is highly recommended and I’m sure broadly used. If you want a non-application solution there are also some config files to edit to get the job done.
Most Applications
Create a file
/home/<username>/Library/KeyBindings/DefaultKeyBinding.dict and add the following:
{
"UF729" = "moveToBeginningOfLine:";
"$UF729" = "moveToBeginningOfLineAndModifySelection:";
"UF72B" = "moveToEndOfLine:";
"$UF72B" = "moveToEndOfLineAndModifySelection:";
"UF72C" = "pageUp:";
"UF72D" = "pageDown:";
} |
Terminal
Terminal preferences
Open Terminal – Preferences – Settings – Keyboard. Edit each of the following setting their action to ‘send string to shell’.
Key Escape Sequence Home 33[1~ End 33[4~ Page Up 33[5~ Page Down 33[6~ |
Now open /home/<username>/.inputrc and add:
"e[1~": beginning-of-line "e[4~": end-of-line "e[5~": history-search-backward "e[6~": history-search-forward "e[3~": delete-char "e[2~": quoted-insert "e[5C": forward-word "e[5D": backward-word "ee[C": forward-word "ee[D": backward-word set completion-ignore-case On |
Other notes
Restart your machine for changes to take affect. Restarting individual applications also works if you can’t restart for whatever reason. I hear Firefox needs its own changes – if you happen to know what those are comment below and I’ll add them in.
