Deactivate specific yasnippets in Emacs

Question

With Yasnippet recently updated from MELPA, I would like to be able to deactivate only the snippets xxx and todo that come with text-mode. The first expands with x and the other with t, which bother me because I write math texts in org-mode and I need to write several x's and t's by themselves, and then press TAB to exit parenthesis.

From yas-buffer-local-condition, it seems that I might be able to do something if there was a #condition: directive in the snippets, but the mentioned snippets don't have one.

I get my way if I just delete the files, but unfortunately they reappear at each update of Yasnippet.

One possible solution would be to control the snippets with key bindings by adding a line of code to each snippet -- e.g., # binding: C-I a b c or # binding: C-I d e f  The combination C-I is equivalent to the tab key and the space between the following letters means that they are pressed individually one at a time. In addition, the following lines of code can also be modified to reflect different key(s): # key: a_b_c and # key: d_e_f.

The variable yas-snippet-dirs can be used to control the location(s) of snippets. It may be a good idea to move snippets to a different location so that they are not touched by future updates (e.g., el-get).

The xxx snippet looks like this:

ORIGINAL

# -*- mode: snippet -*-
# name: xxx
# key: x
# --
`(yas-with-comment "XXX: ")`

MODIFIED

# -*- mode: snippet -*-
# name: xxx
# key: a_b_c
# binding: C-I a b c 
# --
`(yas-with-comment "XXX: ")`

The todo snippet looks like this:

ORIGINAL

# -*- mode: snippet -*-
# name: todo
# key: t
# --
`(yas-with-comment "TODO: ")`

MODIFIED

# -*- mode: snippet -*-
# name: todo
# key: d_e_f
# binding: C-I d e f
# --
`(yas-with-comment "TODO: ")`

For those who are curious, the function yas-with-comment looks like this

(defun yas-with-comment (str)
  (format "%s%s%s" comment-start str comment-end))
