I assume you mean that your remote is limited in available buttons and, 
therefore, you haven't mapped any of the available key bindings to 
buttons on your remote...

The design of jump points was to allow an action that overrides both 
local and global contexts--i.e. it's at the top of the chain--to allow 
you to "jump" from one action/area/context to another.  There was (very 
long) discussion of the idea of allowing local actions to take 
precedence over jumps back in '07, but was decided to be too much of a 
change-of-purpose of jump points and generally could result in 
unexpected behaviors, so it was decided to limit the places in which 
this could be done (i.e. you can map a jump point to Program Guide and 
map the same key in TV Playback context to GUIDE and the local binding 
is explicitly coded to override the jump.

FWIW, you could get the behavior (that IIUC) you want using LIRC 
modes--i.e. hit a button and change the mode of the remote so you have a 
playback mode that maps the buttons to one set of keys and a main mode 
that maps the buttons to other keys (and ...).
