1. Run spell checking. Spell checker dialog opens with the word "Zsli" selected:
   


2. Change the word "Zsli" to "zsli" in edit box and press "Add" button:
   


3. Spell checker goes to a next word and selects "zsli":
   
   
   WTF? I was sure I just added the word "zsli" to dictionary in step 2.

1. Run spell checking. Spell checker dialog opens with word "Xsli" selected:
   


2. Change the word "Xsli" to "Asli" in edit box and press "Change" button:
   


3. Spell checker changes "Xsli to "Asli" and finishes its work.
   
   
   Ooopy! I just made a typo: that word should be "Zsli" - not "Asli".

1. Type " Xsli" without quotes (notice a space in front of the word). The word must not be in dictionary:
   
   
   Undo:
   
   
   Redo:
   
   


2. Type " zxcvb" without quotes (notice a space in front of the word). The word must not be in dictionary:
   
   
   Undo:
   
   
   Redo:
   
   


3. Type " qwert" without quotes (notice a space in front of the word). The word must not be in dictionary:
   
   
   Now there are 3 actions in editor's undo buffer:
   
   


4. Undo some of the actions with the "Undo" button on the "Standard" toolbar (NOT by pressing Ctrl+Z and NOT by selecting "Edit -> Undo" menu item). Number of actions doesn't matter. In this example I undo 2 actions:
   
   


5. Run spell checking. Spell checker dialog opens with the first word ("Xsli") selected:
   
   


6. Click the "Ignore" button. Spell checker goes to the "next" word ("zxcvb"):
   
   


7. Click the "Ignore" button. Spell checker goes to the "next" word ("qwert"):
   
   


8. Click the "Ignore" button. Spell checker finishes its work.
   
   

1. VA do underline words not in dictionary.
   
   


2. VA doesn't underline words not in dictionary.

class CaseMapping {};

// Here, the word "CaseMapping" must not be selected
// by spell checker because it's a symbol defined in
// source code.

1. Spell checker checks value of HTML tag attributes when they are in double quotes, but not when they are in single quotes. Not a big deal, yet I'd prefer spell checker not to check them in any case.
   

   
   // checked here: <a name="XsliDescription">
   // skipped here: <a name='XsliDescription'>
   

   
   


2. This one seems weird. Sometimes spell checker misses a word (or falsely selects a word - it depends on what it's really supposed to do). My best attempt to formalize the issue looks like this:
   

   quote:

   ---

   
   If a word is typed in CamelCase (looks like a class name, but is NOT a class name defined in source files), and that word is not followed either by 1) one or more spaces followed by any symbol except angle "<>" or square "[]" brackets, or 2) \\r\\n, then spell checker misses it.
   

   ---

   
   In the examples below missed instances of the word "XsliDescription" are marked with red and checked instances are marked with blue:
   

   
   // 1 - skipped, 2 - checked, 3 - skipped, 4 - skipped.
   // XsliDescription <a name="XsliDescription">XsliDescription</a> XsliDescription.
   
   // 1 - skipped, 2 - checked, 3 - skipped, 4 - skipped.
   // XsliDescription [a name="XsliDescription"]XsliDescription[/a] XsliDescription.
   
   // Removing the dot after last "XsliDescription", so it's now followed by \\r\\n.
   // 1 - skipped, 2 - checked, 3 - skipped, 4 - checked.
   // XsliDescription <a name="XsliDescription">XsliDescription</a> XsliDescription
   
   // Adding ":" (a colon) after first "XsliDescription".
   // 1 - skipped, 2 - checked, 3 - skipped, 4 - skipped.
   // XsliDescription: <a name="XsliDescription">XsliDescription</a> XsliDescription.
   
   // Adding " " (a space) after first "XsliDescription", so there are two spaces after it.
   // 1 - skipped, 2 - checked, 3 - skipped, 4 - skipped.
   // XsliDescription  <a name="XsliDescription">XsliDescription</a> XsliDescription.
   
   // Adding " :" (a space followed by a colon) after first "XsliDescription".
   // 1 - checked, 2 - checked, 3 - skipped, 4 - skipped.
   // XsliDescription :<a name="XsliDescription">XsliDescription</a> XsliDescription.
