# A key chain with muktzeh items on it is considered a bosis. If the permitted keys are more important it isn't a bosis.<ref>Rav Shlomo Zalman (cited by Dirshu 308:6; see Shemirat Shabbat Kehilchata ch. 20 fnt. 311) explained that unlike a loose leaf where the empty pages in the binder are nullified by the pages with writing, keys on a key chain aren't nullified since each is significant in it of itself. Chazon Ovadia Shabbat v. 3 p. 135 agrees that keys on a key chain are a bosis for the keys and if there's permitted and muktzeh it is permitted.</ref> | # A key chain with muktzeh items on it is considered a bosis.

# If a person left something muktzeh on top of or in a sefer the sefer does become a bosis. Therefore, according to those who hold that blank paper is muktzeh (see [[Books,_Notebooks,_and_Papers_on_Shabbat#Blank_Paper]]) one should be careful not to leave it in a sefer before Shabbat.<ref>Igrot Moshe OC 4:72</ref> | # If a person left something muktzeh on top of or in a sefer the sefer does become a bosis.
