Wherever the \qsemicolon is indicated as a list parser in this guide, it can be replaced by any user-specified one character parser via the package option \fx{keyparser}. To avoid confusing the user-supplied parser with internal parsers, it is advisable to enclose the chosen character in curly braces when submitting it as a package option. The braces will be stripped off internally. Please note that some of the characters that may be passed as a list parser may indeed be active; be careful to make them innocent before using them as a list/key parser. My advice is that the user sticks with the \qsemicolon as the key parser: the chances of it being made active by any package is minimal. If you have the chosen parser as literals in the callbacks of your keys, they have to be enclosed in curly braces.

List processor keys (or lisp keys) are ordinary keys that accept a parser-separated list as a user input and process each element of the list. The key's callback \ang{cbk} is then a list processor, but the key author doesn't have to design and suggest his own looping system. All he has to do is to pass the parameter \fx{#1}, representing the individual items of the list, to the key's callback. The key will internally do the loop and process the list (\ie, the user input).
-Each item will be processed by the key's callback. A lisp key does accept any arbitrary list separator. When the list separator differs from \qcomma, it has to be provided in the key's callback as the argument of the undefined command \fx{\listsep}. And at key-setting time, user inputs that are comma-separated should be enclosed in curly braces, otherwise they won't be parsed properly and errors will arise. An example follows. When setting the key, the user must then use the same list separator. \fx{\ltxkeyslispnr} gives the numerical order of each item in the list. The default value and user input of a lisp key should take cognizance of the list separator. Both the default value and the user input of a lisp key can be just one item, rather than a list; in which case the current input is assumed to have just one item. Spurious leading and trailing spaces (\ie, unprotected spaces) in the list are trimmed before the list is parsed by the key's callback. Reminder: \fx{#1} in the key's callback refers to the individual item of the list, and not the entire list itself.

Sometimes you may want to create keys for which the user must always supply his/her own values, even if the keys originally have default values. The default values of keys may not always be suitable. Take, for example, the height and width of a graphics image. For functions that are meant to handle generic images, it would certainly be inappropriate to relieve the user of the need to call picture height and width without corresponding values.

There are times when it is required to use the same, or nearly the same, set of keys for different functions and purposes, and thus for different key families and prefixes. We call such keys \quoted{cross-family keys} or \quoted{xfamily keys}. Such keys bear the same names across key families and key prefixes. For example, the \pkg'{xwatermark} defines three functions (\ffx'{\xwmminipage,\xwmboxedminipage,\xwmcolorbox}) using nearly the same set of keys. In each of the three families, the keys bear the same or similar names and they have similar callbacks. The management of cross-family keys can be simplified by using the tools of this section. Even if not all the cross-family keys are needed in all the families to which they may belong, there are still advantages in using this type of keys when some of the keys cut across families.

+The command \fx{\ltxkeys} simply provides an ungrouped\footnote{Meaning no local groups are created.} environment for using the short forms of the commands shown in \sref{tab:ltxkeys-cmdabbrv}. The abbreviated commands are pushed on entry into \fx{\ltxkeys}, they are then assigned the meaning of their longer counterparts, and then popped (to whatever their original meaning was before entry into \fx{\ltxkeys}) on exist of \fx{\ltxkeys}. The list parser within \fx{\ltxkeys} is invariably \quotedfx{\\}. The list is normalized\footnote{Normalization implies replacing double \quotedfx{\\} by single \quotedfx{\\} and removing spurious spaces around each \quotedfx{\\}.} and the given codes \ang{code-i}, $i=1,...,n$, executed on the consecutive loops. The commands \ffx{\ordkeys,\cmdkeys}, \etcc, can be used to define just one key or multiple keys in the same family and of the same callback. \sref{tab:ltxkeys-cmdabbrv} lists the other abbreviations available within \fx{\ltxkeys}.
+
+The \stform of \fx{\ltxkeys} will expand its argument once before commencing the loop and executing the codes \ang{code-i}, $i=1,...,n$. The \pmform is equivalent to invoking the package option \fx{endcallbackline} before calling \fx{\ltxkeys}. Using both \redstar and \redprime makes \hx{\endlinechar} $-1$ but the effect is not enforced, since in the \stform of \fx{\ltxkeys} the argument has already been read.

\begin{enum}
-\item If an item contains \ang{parser}, it must be wrapped in curly braces when calling the command \fx{\ltxkeysdolist}, otherwise the elements may be mixed up during parsing. The braces will persist thereafter, but will of course be removed during printing (if the items are printed).
-\item White spaces before and after the list separator are always ignored by the normalizer called by \fx{\ltxkeysdolist}. If an item contains \ang{parser} or starts with a space, it must, therefore, be wrapped in curly braces before calling \fx{\ltxkeysdolist}.
-\item Since when \ang{flag} is $0$ or $2$ the command \fx{\ltxkeysdolist} doesn't call the normalizer, in this case it does preserve outer/surrounding spaces in the entries.

-Sometimes you may want to modify the macro of an existing key. For some reasons, redefining the key may not be the best option, besides being uneconomical.
-
-The following \fx{\ltxkeyspatchcallback} command and use syntax can be utilized to patch/modify existing key macros. In rare circumstances one may wish to modify an subsisting key macro, especially one defined in an existing package, without redefining the key afresh. Key macros are intrinsically parameterized functions and \latex kernel's \fx{\g@addto@macro} can't be used to patch parameterized functions.

-Here, \ang{keyprefixes} and \ang{families} are comma-separated lists of key prefixes and families; \ang{key-1} to \ang{key-n} are key names; \ang{search-1} to \ang{search-n} are the search patterns, and the quantities \ang{replace-1} to \ang{replace-n} the corresponding replacement texts. \ang{fallback-s} and \ang{fallback-f} are the actions that should be taken if the patching succeeds or fails for any of the existing keys. \fx{\ltxkeyspatchcallback} loops over the given key prefixes and families to find the listed keys. If a key can't be located (in terms of being previously defined), it is ignored and a warning message is logged (if the package option \fx{verbose} is enabled). Within the \ang{fallback-s} and \ang{fallback-f} blocks, you can use \fx{\ltxkeyscurrentkey}, \fx{\ltxkeyscurrentfamily}, and \fx{\ltxkeyscurrentprefix} to refer to the current key name, family and prefix (see example below). The \clsign instructs \fx{\ltxkeyspatchcallback} to globalize the outcome; the \stsign is explained below.
+\docsection(sec:addkeycode){Adding to key macros}
-Also, within the search-and-replace block you can use \fx{#1} to refer to the parameter of the key macro, which ordinarily corresponds to the value of the current key. There is no need to double the parameter character. But if you're introducing a new parameterized command within this block, you would need to double the parameter character.
-White spaces between the key name and the search pattern are ignored within the block of key names and search and replacement patterns. You can insert \fx{\ltxkeysbreaklist} within this block to prematurely break out of the loop. The remaining elements of the list will be saved in \fx{\ListRemainder} (see \cref{sec:list-process}).
-
-The default list parser in \fx{\ltxkeyspatchcallback} is the semicolon (\fx{;}). This can be changed by using \fx{\ltxkeysdeclarekeypatchparser}, which takes only one argument (the list parser).
