Please don't require multi-clicks (double, triple) anywhere (or for that 
matter, any operation where timing is critical). Even I sometimes have 
trouble doing those, not to mention lots of adults I've watched using 
Windows. They also don't seem to understand the distinction between 
single and double clicks, usually doing double or even triple clicks for 
virtually any operation that doesn't provide instant (<< 100ms) 
response.

What actions would be sensible to do on all entries? How often would a 
user want to execute it on all entries?
Depending on the answers to those questions a viable option might be to 
just split up the action into "[action] on selected entries" and 
"[action] on all entries". Maybe even a submenu "[action]" -> "on this 
entry", "on selected entries", "on all entries".

Traditional UIs provide "Select All" and "Select None" in a menu. So one 
option would be to add "Select all entries" to the contextual toolbar in 
[1].

All of those sound much better to me than requiring timing constraints 
to be met.
