It all depends on specific shell implementation (you might have different default shell on different systems or even for different users within a single system, e.g. bash, ksh, tcsh, etc).
Also it depends on shell itself.
E.g. bash supports two modes: emacs and vi. Each mode has its own shortcuts (emacs or vi like). To change it you have to execute set -o emacs (normally it's a default one) or set -o vi
You can find more information in your specific shell documentation.

When not in emacs editing mode, the Ctrl-A and Ctrl-E have no special significance. If the echoctl stty/termios setting is on, all control keys which are not handled specially will be displayed in the ^A, ^X, etc, "caret" notation.
Many shells (like ksh or zsh) will determine the default editing mode (vi or emacs) based on the values of VISUAL and EDITOR environment variables (in this order of precedence, and also handling variants like vim, elvis, xemacs, etc).
This was broken (very annoyingly!) in mksh, but it's also still the case in other pdksh-derived shells.
Other shells like bash or tcsh default to the emacs editing mode, but that may also be overridden from the configuration file of the editing library (eg. set editing-mode vi in ~/.inputrc for the readline library used by bash).

This was broken (very annoyingly!) in mksh, but it's also still the case in other pdksh-derived shells.
Other shells like bash or tcsh default to the emacs editing mode, but that may also be overridden from the configuration file of the editing library (eg. set editing-mode vi in ~/.inputrc for the readline library used by bash).
