// when you're trying to use `position:sticky` on an element
// you'll have trouble if any parent/ancestor element has
// overflow set to anything other than "visible" (such as: auto,hidden,overlay,scroll)
// & turns out if a parent is `display:flex` it might need some love
// (to remedy this you can set the `align-self` of your sticky element)
// see here for how the display & align-self properties affect: http://bit.ly/2ZaRu4o 

// so, to find those troublesome parents...
// copy & paste this into Chrome Inspector/Dev Tools console
// (and be sure to change the #stickyElement below, if needed)

copy/delete word under cursor in Vim
yw / byw

Assuming that the cursor is at the first character of the word simply do this in command mode:
     yw
y is for yank and w is for word.

Other ways of doing the same thing which are not as efficient:
     vey
the v starts visual select mode. e tells vim to move to end of word. y yanks or copies the word. to delete replace y with x.
