FreeBSD 10.2 (US English). Console Mode - No GUI

Developing a custom layout on Latin Alphabet.

Queries

1. Where can I find the existing keymaps so that I can edit them?
2. How to replace my existing layout with the custom layout?
3. How to revert back to old layout if anything goes wrong?

Now say I want to output
ä on pressing [ ALT-GR + a ] and
Ä on pressing [SHIFT + ALT-GR + a]

In Windows all I did was put in the appropriate Unicode value of the character in the ALT-GR position in the Microsoft Keyboard Layout Creator. In this file I don't understand certain things. What are ht,bs,slock,fkey49 to fkey64?

Code:
087 [b]fkey11[/b] fkey23 fkey35 fkey47 scr11 scr11 scr11 scr11 O 
088 [b]fkey12[/b] fkey24 fkey36 fkey48 scr12 scr12 scr12 scr12 O
Not sure what ht is, but I'm guessing bs is BackSpace. slock is ScrollLock.

Edited the file us.iso.kbd and made a new custom layout file us.iso.cust.kbd.
Changed the the new layout to the custom using kbdmap .
The Terminal was giving problems as it was not setup to UTF-8, when trying to input ä and Ä.
Modified the .login_conf, now it works.

The Localization and Console Setup page of the FreeBSD handbook is very complex to understand.
