Virtual Key Symbolic Names
The Virtual Key Symbolic Names provide a convenient notation for specifying certain control characters to be transmitted into the input buffer in response to a click event on the control; See the CONTROL class cmd parameter, the XTREE XTR.kbdstr, the XTEXT TXC.kbdstr, etc.) The names all start with VK_ followed by the name of the key as it relates to the keyboard. The names in the table below can also be altered to indicate the SHIFT or CONTROL version by inserting a “^” and/or lower case “s” after the underscore. For example, “VK_^UP refers to the keystroke Control-Up Arrow, “VK_sDOWN” refers to Shift-Down Arrow, and “VK_^sF2” refers to Control-Shift-F2.
Note that the Virtual Key Symbolic Names can optionally be enclosed in percentage signs ("%"), e.g. "%VK_RIGHT%", which act only as syntax delimiters. Such delimiters would be unnecessary and superfluous in most cases, except in the case where multiple Virtual Key Symbolic Names are being combined. For example, to encode the sequence TAB followed by ENTER, you would need to use the format "%VK_TAB%%VK_ENTER%", since "VK_TABVK_ENTER" would not be properly recognized.
