I found a misspelled word ("retreive") in a comment, so, instead of doing what I usually do (right-click on it), I thought I'd use the keyboard context-menu key (don't know the real name for it).
Instead of bringing up the spell-checker's list of suggestions, it brought up the standard IDE's context menu.
Our context menu appears when you Shift+Right+Click in the source window, Right+Click the selection margin or press Shift+Application in a source window (Application key is between the Alt and Ctrl keys on the right side of most keyboards.) The context menu appears whether or not you are on a misspelled word.
Right+Click on a misspelled word opens our spell checker.
We assume you want keyboard access to fix the spelling of the current word. Your request is reasonable. Perhaps we will make VAssistX.SpellCheck open a list of choices if the current word is misspelled. As it is, VAssistX.SpellCheck checks the selection or document.
We intend to revamp the Context menu of VA X. The currrent one is a bit dated. We hope to get to the task sometime after beta.
