* basic logic working * Added a literal for ignore flag which cna be shared by all the files * Added a condition that the other modifier keys should not be pressed * Added comments to describe each scenario * sometimes when multiple modified keys were involved the shift+tab key press was also being invoked, so added an additional check in the IsValid function * use variable for vk_tab * remove new line before initializing dwextraInfo * move flag check if the filterKeyboardevent function * use windows.system.virtualkey.shift instead of defining a constant for the shift key code * removed latest settings to use internal settings instead. Removed the validity check while still within the hotkey other than if it's tab or shift+tab * add a function to send input to the system instead of duplicating the send input code * remove VKSHIFT declaration * display all shortcuts/keys except tab and shift+tab * remove header that is no longer needed
