Mudlet uses Perl regular expression aliases. Regexes are a special way of matching patterns of words. For the beginners it is enough to think of them as a general way to specify the words itself and their placement within the line. For basic aliases it is enough to know that the character ^ symbolizes the beginning of the line and the character $ symbolizes the end of the line. If you want to make an alias "tw" that sends the command "take weapon", you don’t have to care about placement or pattern matching in general. All you need to do is fill ^tw$ in the field called "Regex" and type take weapon in the field called "substitution". Then you need to save the new alias by clicking on the "Save" icon in the top middle. The symbol for unsaved items disappears and makes way for a little blue checkbox. If this box is checked the alias is active. If the blue box is empty, the alias is deactivated and will not work unless you press the "activate" toggle padlock icon. Now you are ready to go. Type "tw" in the command line and press the enter key. Mudlet will send "take weapon" to the MUD. Aliases are basically a feature to save you a bit of typing (much like buttons which will be described in detail in a later section of the manual). More advance alias usage will be described later in the manual.
