OS X (El Capitan) Terminal Fn-Up and Fn-Down stop working as Page Up and Page Down

In addition to VxJasonxV’s answer (which is correct), if you want to modify your terminal behavior so using up or down does a pageup/pagedown in vim (and others), you can go to:

Terminal -> Preferences -> Click on the Settings Toolbar, then the Keyboard Tab.

Add a new keys like this: (showing one example below)

• Page Up: \033[5~
• Page Down: \033[6~
• Home: \033[4~
• End: \033[1~

Here’s an example with the “Cursor up”:

Now you can press Up/Down and it will do the pageup/down. I suggest you add a modifier (like Control). Sadly, you can’t use the “Fn” key as a modifier.

Note: By default, Control + Cursor Left is delete until the end of the line and control+cursor right is insert (in vim at least), so you can use another modifier if you don’t want to change those.

I'm using the following.

Have a shell command, called myssh, with content:

PROFILE="$1";shift;
DEF="Basic" #the default profile name
echo "tell app \"Terminal\" to set current settings of first window to settings set \"${PROFILE}\""|osascript
ssh $@
echo "tell app \"Terminal\" to set current settings of first window to settings set \"${DEF}\""|osascript

and use bash aliases for the connect, like:

alias ssweb='myssh Homebrew user@web.example.com'
alias ssmail='myssh Ocean me@mail.example.com'

When I want to ssh into the web server, I simply write ssweb in the Terminal and I got the "Homebrew" profile. When the ssh session ends, the AppleScript sets back to the "Basic".

The aliases should go into your $HOME/.profile or similar bash-startup file.

The "Homebrew", "Ocean" etc. are the setting profiles from the Terminal.app preferences. You can also set up different fonts, encodings, etc.

Of course, you can use it directly (without aliases) like:

myssh Pro user@another.machine.example.com
       ^        ^
       |        ssh command arguments
       terminal profile name
