If I want to kill one buffer I use command
As result I can kill ONE desire buffer. But suppose I need to kill the next buffers:
build.gradle, approfile.json, cascade.update.txt
How I can do this quickly?
ido isn't designed for that; use the buffer list instead.
C-x C-b opens a buffer containing a list of all buffers that are open. In this buffer you can use
C-k to mark buffers to be deleted, then
x to delete all marked buffers. Since it's a full buffer, you can also use
C-s to search it.
