Usage
History recall allows a previous statement to be quickly recalled and re-executed. It's a very fast shorthand, especially in the edit/compile/debug loop or to fix a typo. For convenience, ! is taken as an ordinary character if followed by white space, =, ~ or (.
If you want, you can choose different characters to introduce history references by changing the histchars variable.
