10. Advanced text options (+)

Sometimes, you may want to set a piece of text in bold face. Or you want to emphasize it by using an italic font. In TeX/LaTeX a general concept named "grouping" is used. A "group" consists of an opening brace "{", arbitrary text and the closing brace "}". So in the input sentence

This is {a small} example.

the text "a small" is "grouped" now. For changing the font style you have to use the appropriate TeX/LaTeX command. All commands begin with the backslash "\", immediately followed by the name of the command. This is "bf" for "bold face" and "em" for "emphasize", i.e. an italic face font. If you wanted to set the "grouped" text in bold face you would have to enter

This is {\bf a small} example.

as input. Using "\em" as command yields the text in italic face. These kind of font changes are "local", i.e. they affect only the inner group. That is why the word "example" is not set to bold or italic face anymore, the "group" stops right after the word "small" with the closing brace "}". If this brace would not be there, all the rest of the input text would be set to bold or italic face, respectively. Thus, it is important that you provide a closing brace "}" for each opening brace "{" in the input.

ChessTask can help you with this. If you have activated one of the text fields Title of the task, Task or Solution you can click on one of the "text command" buttons Bold Face or Italic Face. Then, a pair of braces "{}" is automatically inserted into the selected text field, together with the correct command (either "\bf" or "\em"). Additionally, the cursor is positioned right before the closing brace "}", such that you can immediately type the words you want to set to bold or italic face. Afterwards, you have to reposition the cursor to the end of the text---or outside of the group, at least---in order to continue with entering "normal" text.

Another "group" that is provided by the LaTeX style file `skak.sty' looks a bit different because it starts with a command and then the grouping characters "{}" follow. Any text between an opening "\movecomment{" and a "}" for closing the group, is interpreted as a list of chess moves. If you click on the Move button these delimiters are inserted into the currently active text field. Within this environment certain characters get a new and special meaning:

If you would like to see an example for "move" groups, have a look at the file example.tsk from the examples.

You can also mix the "move" environment with the usage of bold or italic faced fonts like I did in the test of the Informator symbols. Then you have to obey the following rule: You can not include a "bf" or "em" font face selection within a "movecomment" but have to do it the other way round.

For the first moves of the "symbol test" I entered

{\bf \movecomment{1. e4 e5 2. Sf3 Sc6 3. d4 exd4 4. Sxd4 Lc5
5. Le3 Df6 6. c3 Se7 7. Lc4 Se5 8. Le2 Dg6 9. 0-0 d6 10. f3}}
\movecomment{[10. Tfd1 \see{} 23.4]} {\bf \movecomment{0-0 11. Kh1}}
\movecomment{[11. Td8 Sd8 12. Td1 Lb7 13. Sd2 Sc6 \see{} 24.1;
13. ..., Se6!?\equal]}

using ChessTask switched to "German".

From now on, you are allowed to use the characters "{}\" in your input texts because you (hopefully) know their meaning.
