Been hot on a new [old] project recently and I’ve not only been coding my ass
off, but delving into some territory that I haven’t delved into as of late.
The latest is in terms of determining if a modifier key has been pressed in
conjunction with another key press. So like,
Shift being help while a letter
or other key has been tapped.
Turns out, you can detect these modifier quite easily, and there are
values on the
event object for all of the major modifier keys like control,
alternate and such.
When interrogating an
event object, you can simply look for the following
event.altKey– For when the alternate (alt) key is being held.
event.ctrlKey– For when the control key is being held.
event.shiftKey– For when the shift key is being pressed (allows you to
differentiate between upper and lower cased letters being pressed.
event.metaKey– For when the meta (super) key is being held.
Checking the aforementioned values in addition to
event.key makes it easy to
determine if the user is pressing
Ctrl+F and the like.
