The GNML tags and parameters are embedded in tag brackets. These are special characters that look like ">" and "<", but they're special codes indeed. The ">" character is an "opening bracket" and is placed BEFORE a GNML tag. The "<" character is the "closing bracket" and it is placed AFTER a GNML tag and all its parameters (if any).

There must be a space between the tag name and it's first parameter (if any).

Each pair of brackets may contain only one tag. Do not enter more tags within the same brackets.

If a tag has more than one parameter, type them all inside the same pair of tag brackets, as >auto 4,12pt,100,1,1,100,0pt,141.24pt<.

Do not type the tag brackets by hitting the ">" and "<" keys on the keyboard. If you do this, the brackets will be inserted in the text, and they will be interpreted as if they were the characters "greater than" and "smaller than", not as the tag brackets. Use the hot-key >(typically F9), or menu command (see Tags related options in menus and shortcuts).

Respect the case sensitivity of tags: >hld 9001< is not the same as >HLD 9001<.

When entering quotes for tags parameters, have in mind that the shortcut keys for single and double quotes are usually assigned to smart quotes, and not to straight ones. But the smart quotes won't work as delimiters for parameters. Thus, to get straight quotes, use SHIFT+CTRL+ALT+<doublequote> key, and SHIFT+CTRL+ALT+<singlequote> key.
