+					*g:yaml_schema* *b:yaml_schema*
+A YAML schema is a combination of a set of tags and a mechanism for resolving 
+non-specific tags. For user this means that YAML parser may, depending on 
+plain scalar contents, treat plain scalar (which can actually be only string 
+and nothing else) as a value of the other type: null, boolean, floating-point, 
+integer. `g:yaml_schema` option determines according to which schema values 
+will be highlighted specially. Supported schemas are
+
+Schema		Description ~
+failsafe	No additional highlighting.
+json		Supports JSON-style numbers, booleans and null.
+core		Supports more number, boolean and null styles.
+pyyaml		In addition to core schema supports highlighting timestamps, 
+		but there are some differences in what is recognized as 
+		numbers and many additional boolean values not present in core 
+		schema.
+
+Default schema is `core`.
+
+Note that schemas are not actually limited to plain scalars, but this is the 
+only difference between schemas defined in YAML specification and the only 
+difference defined in the syntax file.

-   Vim ist ein sehr mächtiger Editor, der viele Befehle bereitstellt; zu viele,
-   um alle in einem Tutor wie diesem zu erklären.  Dieser Tutor ist so
-   gestaltet, um genug Befehle vorzustellen, dass Du die Fähigkeit erlangst,
-   Vim mit Leichtigkeit als einen Allzweck-Editor zu benutzen.
-   Die Zeit für das Durcharbeiten dieses Tutors beträgt ca. 25-30 Minuten,
-   abhängig davon, wie viel Zeit Du mit Experimentieren verbringst.
-
-   ACHTUNG:
-   Die in den Lektionen angewendeten Kommandos werden den Text modifizieren.
-   Erstelle eine Kopie dieser Datei, in der Du üben willst (falls Du "vimtutor"
-   aufgerufen hast, ist dies bereits eine Kopie).
-
-   Es ist wichtig, sich zu vergegenwärtigen, dass dieser Tutor für das Anwenden
-   konzipiert ist. Das bedeutet, dass Du die Befehle ausführen musst, um sie
-   richtig zu lernen. Wenn Du nur den Text liest, vergisst Du die Befehle!
-
-   Jetzt stelle sicher, dass Deine Umstelltaste NICHT gedrückt ist und betätige
-   die   j   Taste genügend Male, um den Cursor nach unten zu bewegen, so dass
-   Lektion 1.1 den Bildschirm vollkommen ausfüllt.
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-			Lektion 1.1: BEWEGEN DES CURSORS
-
-  ** Um den Cursor zu bewegen, drücke die h,j,k,l Tasten wie unten gezeigt. **
-	     ^		 Hilfestellung:
-	     k		 Die h Taste befindet sich links und bewegt nach links.
-       < h	 l >	 Die l Taste liegt rechts und bewegt nach rechts.
-	     j		 Die j Taste ähnelt einem Pfeil nach unten.
-	     v
-  1. Bewege den Cursor auf dem Bildschirm umher, bis Du Dich sicher fühlst.
-
-  2. Halte die Nach-Unten-Taste (j) gedrückt, bis sie sich wiederholt.
-     Jetzt weißt Du, wie Du Dich zur nächsten Lektion bewegen kannst.
-
-  3. Benutze die Nach-Unten-Taste, um Dich zu Lektion 1.2 zu bewegen.
-
-Bemerkung: Immer, wenn Du Dir unsicher bist über das, was Du getippt hast,
-	   drücke <ESC> , um Dich in den Normalmodus zu begeben.
-	   Dann gib das gewünschte Kommando noch einmal ein.
-
-Bemerkung: Die Cursor-Tasten sollten ebenfalls funktionieren.  Aber wenn Du
-	   hjkl benutzt, wirst Du in der Lage sein, Dich sehr viel schneller
-	   umherzubewegen, wenn Du Dich einmal daran gewöhnt hast. Wirklich!
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-			    Lektion 1.2: VIM BEENDEN
-
-
-  !! ACHTUNG: Bevor Du einen der unten aufgeführten Schritte ausführst, lies
-     diese gesamte Lektion!!
-
-  1. Drücke die <ESC> Taste (um sicherzustellen, dass Du im Normalmodus bist).
-
-  2. Tippe:	:q! <ENTER>.
-     Dies beendet den Editor und VERWIRFT alle Änderungen, die Du gemacht hast.
-
-  3. Wenn Du die Eingabeaufforderung siehst, gib das Kommando ein, das Dich zu
-     diesem Tutor geführt hat. Dies wäre:	vimtutor <ENTER>
-
-  4. Wenn Du Dir diese Schritte eingeprägt hast und Du Dich sicher fühlst,
-     führe Schritte 1 bis 3 aus, um den Editor zu verlassen und wieder
-     hineinzugelangen.
-
-Bemerkung:  :q! <ENTER>  verwirft alle Änderungen, die Du gemacht hast. In
-     einigen Lektionen lernst Du , die Änderungen in einer Datei zu speichern.
-
-  5. Bewege den Cursor abwärts zu Lektion 1.3.
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-		     Lektion 1.3: TEXT EDITIEREN - LÖSCHEN
-
-
-	 ** Drücke  x  um das Zeichen unter dem Cursor zu löschen. **
-
-  1. Bewege den Cursor zu der mit ---> markierten Zeile unten.
-
-  2. Um die Fehler zu beheben, bewege den Cursor, bis er auf dem Zeichen steht,
-     das gelöscht werden soll.
-
-  3. Drücke die  x  Taste, um das überflüssige Zeichen zu löschen.
-
-  4. Wiederhole die Schritte 2 bis 4, bis der Satz korrekt ist.
-
----> Die Kkuh sprangg übber deen Moond.
-
-  5. Wenn nun die Zeile korrekt ist, gehe weiter zur Lektion 1.4.
-
-Anmerkung: Während Du durch diesen Tutor gehst, versuche nicht, auswendig zu
-    lernen, lerne vielmehr durch Anwenden.
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-		     Lektion 1.4: TEXT EDITIEREN - EINFÜGEN
-
-
-		    **  Drücke  i  , um Text einzufügen. **
-
-  1. Bewege den Cursor zur ersten unten stehenden mit ---> markierten Zeile.
-
-  2. Um die erste Zeile mit der zweiten gleichzumachen, bewege den Cursor auf
-     das erste Zeichen NACH der Stelle, wo der Text eingefügt werden soll.
-
-  3. Drücke  i  und gib die notwendigen Ergänzungen ein.
-
-  4. Wenn jeweils ein Fehler beseitigt ist, drücke <ESC> , um zum Normalmodus
-     zurückzukehren.
-     Wiederhole die Schritte 2 bis 4, um den Satz zu korrigieren.
-
----> In dieser ft etwas .
----> In dieser Zeile fehlt etwas Text.
-
-  5. Wenn Du Dich mit dem Einfügen von Text sicher fühlst, gehe zu Lektion 1.5.
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-		     Lektion 1.5: TEXT EDITIEREN - ANFÜGEN
-
-
-		     ** Drücke  A  , um Text anzufügen. **
-
-  1. Bewege den Cursor zur ersten unten stehenden mit ---> markierten Zeile.
-     Es ist gleichgültig, auf welchem Zeichen der Zeile der Cursor steht.
-
-  2. Drücke  A  und gib die nötigen Ergänzungen ein.
-
-  3. Wenn das Anfügen abgeschlossen ist, drücke <ESC>, um in den Normalmodus
-     zurückzukehren.
-
-  4. Bewege den Cursor zur zweiten mit ---> markierten Zeile und wiederhole
-     die Schritte 2 und 3, um den Satz zu korrigieren.
-
----> In dieser Zeile feh
-     In dieser Zeile fehlt etwas Text.
----> Auch hier steh
-     Auch hier steht etwas Unvollständiges.
-
-  5. Wenn Du dich mit dem Anfügen von Text sicher fühlst, gehe zu Lektion 1.6.
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-		       Lektion 1.6: EINE DATEI EDITIEREN
-
-
-     ** Benutze  :wq  , um eine Datei zu speichern und Vim zu verlassen. **
-
-  !! ACHTUNG: Bevor Du einen der unten aufgeführten Schritte ausführst, lies
-     diese gesamte Lektion!!
-
-  1. Verlasse den Editor so wie in Lektion 1.2:  :q!
-
-  2. Gib dieses Kommando in die Eingabeaufforderung ein:  vim tutor <ENTER>
-     'vim' ist der Aufruf des Editors, 'tutor' ist die zu editierende Datei.
-     Benutze eine Datei, die geändert werden kann.
-
