Deletion
M-\ (which is bound to delete-horizontal-space) deletes all of the spaces and tabs around the point. M-Space (which is bound to just-one-space) deletes the spaces and tabs around the point leaving just one space. M-^ (which is bound to delete-indentation) joins the current line and the previous line by deleting any indentation and the newline. These all work the same as GNU Emacs.
Killing
C-k (which is bound to kill-line) kills from the point to the end of the line. If the line is blank, it kills the newline. C-w (which is bound to kill-region) kills the region. M-z (which is bound to zap-to-char) prompts for a character to search for, then kills everything upto and including that character. These work the same as GNU Emacs.
Kill Ring
C-y (which is bound to yank) reinserts the text of the most recent kill. M-w (which is bound to kill-ring-save) copies the contents of the region to the kill ring. M-C-w (which is bound to append-next-kill) will cause the next kill to append to the last one. M-y (which is bound to yank-pop) must immediately follow a yank; it will take you to earlier and earlier kills. These all work the same as GNU Emacs.
Accumulating Text
M-x append-to-buffer copies the region to the specified buffer; the point in the specified buffer is left after the copied text. M-x prepend-to-buffer copies the region to the specified buffer; the point in the specified buffer is left before the copied text. M-x copy-to-buffer copies the region to the specified buffer after deleting the specified buffers old contents. M-x insert-buffer copies the contents of the specified buffer into the current buffer at the point. These all work the same as GNU Emacs. append-to-file is currently not supported by Tint Emacs.
