Does anybody know what sgr stands for when using tput? It is supposed to reset the colour scheme to its default colour.

sgr is short for "Select Graphic Rendition", which is also known as "Set Attribute" (see the terminfo(5) manual; man 5 terminfo).
What you are most likely using is sgr0 though, which resets all set attributes.

Can this be done with tput, or am I asking too much?

No, tput won't do this (normally) because you're likely to use only the predefined/standard terminal capabilities, which don't have that combination.

I've got PCManFM and Xfe as graphical file managers in my Arch Linux with Openbox.
When I click on the Trash link in PCManFM I get an error saying "Operation not supported".
Question: Where do PCManFM and xfe put files you sent to the Trash? Thanks.

You need to install gvfs to get PCManFM's Trash Can to work.
It stores the files in the FreeDesktop standard location: ~/.local/share/Trash/files

I use trash-put to trash files from command line. Recently, I had aliased my rm command to trash-put so that I don't accidentally delete something important.

Those files you removed may actually still be opened by another process. In that case the file space will become available when that process closes it's handle to the file.

This is a bit late, but I ran into the same issue. As it turns out, you have to disable the 'Erase files on removable media instead of "trash can" creation' preference. Apparently PCManFM sees any drives with an unmount button as removable media. Once that's done, sending files to trash works as expected.

Moving a file to Trash does not delete the file - it simply stores it in a folder named "Trash" - you can retrieve files moved there so you don't get a prompt checking if you want to delete them when moving them there (as you are simply storing them somewhere else in the filesystem, not deleting them).
