How do I remove this cabinet drawer?

Question

I have a bathroom cabinet drawer that needs to be removed so I can repair the bottom. I can't figure out how to remove it. What do I push or pull to get it out?

This is the drawer fully extended:

A close up, fully extended:

A close up, pushed in a bit. Note the pointy black plastic piece is now inside the slide. Note also the button at the left edge of the T. No amount of pushing in the button while sliding the drawer in and out unlatched it:

The pointy thing does go up and down, but I couldn't get anything to release by moving it.

Answer 1

Push up on the pointy thing and pull on the drawer. see details here

Answer 2

I recently had to remove and replace twelve drawers of this type, in two adjacent bedroom dressers.

@Jack (in Comments on March 24, 2017) has it correct: one lever must be nudged up, while the lever on the other side of the drawer must be nudged down at the same time. Open the drawer so the levers are visible, nudge one up and other down, and the drawer will slide right off the tracks.

I don't remember which lever had to go up and which lever had to go down. I probably did it a few times both ways, until I figured it out. Once I learned which way worked, it worked every time without failure.

When re-fitting the drawer, it is not necessary to extend the slide from the cabinet, nor is it necessary to hold the levers as described above. Just fit the end of the drawer into the slide, and push the drawer into place.

Answer 3

This worked! I also pushed down on the convex of the lever on the left, while lifting the convex on the right and simultaneously pulling out the drawer.
