I write as many of my macros I can using current tiddler so they can be used in 
different ways and depend on less parameters. 

When you generate a list in a filter they are considered tiddler titles and use 
current Tiddler unless you set variable=varname.

Macros based on current tiddler are often valid in others lists.

An increasing number know it well, everyone in this thread are arguably 
experts. Its beauty is its flexibility. In reality macros are a very simple 
extensions of wiki text and widgets. Although its strength is in filters but 
these are very powerful and needs new concepts for many.

Those who have taken this journey and the gurus are paving the way for the next 
generation through support and development.

Enjoy the virtuose circle.

Thanks, Tony!

I'm wondering how many people on earth really understand the TiddlyWiki 
macro language :-)

Why do you use *currentTiddler* as variable?

 Hi all,

 I often use the *kbd* tag for showing (keyboard) keys in my 
 TiddlyWiki, like that:

 Ctrl+Shift+A

 Typing this a lot is no fun, so I made a macro:

 \define key(text: "Shift") $text$

 It can be used this way:

 <>

 Now I could call this macro two or three times for creating a key 
 combination. But it's even easier with additional macros:

 \define combo2(key1: "Ctrl", key2: "x") $key1$+$key2$>>> kbd>

 \define combo3(key1: "Ctrl", key2: "Shift", key3: "x") $key1$<
 /kbd>+$key2$+$key3$

 So I can write:

 <>

 which generates the key combination of my example at top.

 Just for curiosity:
 Is is possible to create a single macro that works for either one, two 
 or three keys? 

 Best regards,
 Max

Personally I have a different approach to this; and it is more general in 
use. Paste this onto Tiddlywiki.com

   - If you are only making use of space delimiters anyway, do it yourself 
   in a single parameter
   - This below defaults to space delimiter and + separator as you wish
   - By using comma you can do the same for multiple words
   - By using "/" you can make a system tiddler easier to read


\define keys(string delim:" " sep:"+")

[MaxGyver]

@Mat: Thanks for your reply! Yes, I know that I can pass empty strings as 
arguments but I don't want to end up with empty keys. And I had no idea how 
to skip a key if an empty string was given.

@Eric: Awesome! This works perfectly. Thank you!

This will do what you want:
\define showkey(key1,key2,key3)
\whitespace trim
$key1$
<$reveal text="$key2$" type="nomatch" default="">+$key2$
<$reveal text="$key3$" type="nomatch" default="">+$key3$
\end

With the above macro, you can then write any of the following
<>
<>
<>

Note: The <$reveal> widget usually takes a "state" parameter, which is the 
name of a tiddler containing a text field with the value to compare.  By 
omitting the "state" parameter, and using the "default" parameter instead, 
you can use $reveal to compare two literal values, without needs a tiddler 
in which to store a state value.

enjoy,

Macros themselves don't require that all arguments are actually used. If 
all are needed depends only on the logic that you create inside the macro. 

\define foo(bar, baz) $bar$ and $baz$

<> ---> YO and

However be careful because the first argument that you put in the macrocall 
is interpreted as the first parameter. So you must either specify which 
parameter:

<> -> and YO

(in this particular case, because there are no spaces in YO, it could 
actually be merely bar:YO )

or give an empty argument

<>  -> YO and
