Buffers
C-x b (which is bound to switch-to-buffer) and C-x 4 b (which is bound to switch-to-buffer-other-window) works the same as GNU Emacs. C-x C-q works the same as GNU Emacs except that it is bound to toggle-read-only. C-x k (which is bound to kill-buffer) works the same as GNU Emacs.
C-x C-b (which is bound to list-buffers) and M-x buffer-menu work the same as GNU Emacs except for the following: m (which is usually bound to buffer-menu-mark) and v (which is usually bound to buffer-menu-select) are currently not supported.
rename-buffer is used to change the name of the current buffer. rename-uniquely is used to give the current buffer a new unique name by appending a number to it if necessary. kill-some-buffers prompts you for each buffer on whether or not to kill it. These work the same as in GNU Emacs.
Visiting Files
C-x C-f (which is bound to find-file) will visit a file. C-x C-r (which is bound to find-file-read-only) will visit a file, but in a read only buffer. C-x C-v (which is bound to find-alternate-file) will visit a different file instead of the current one. C-x 4 f (which is bound to find-file-other-window) will visit a file in another window. find-file-literally is supported; in Tint Emacs it is the same as find-file. All of these work the same as in GNU Emacs.
Saving Files
C-x C-s (which is bound to save-buffer) will save the current buffer to its visited file. M-~ (which is bound to not-modified) will cause Tint Emacs to forget that the current buffer was modified. C-x C-w (which is bound to write-file) will write the current buffer to a specified file. C-x s (which is bound to save-some-buffers) will ask you one by one if you want to save buffers which are currently modified. M-x set-visited-file-name changes file name under which the current buffer will be saved. These all work the same as GNU Emacs, except that save-some-buffers does not support C-r to view the current buffer.
Directories
C-x C-d (which is bound to list-directory) displays a brief directory listing. C-u C-x C-d displays a verbose directory listing. make-directory creates a directory. delete-directory removes a directory. These work the same as GNU Emacs.
Other File Operations
insert-file inserts the specified file into the current buffer at the point. write-region writes the region of the current buffer into the specified file. delete-file deletes the specified file. It does not ask for confirmation. These work the same as in GNU Emacs.
view-buffer, rename-file, copy-file, add-name-to-file, and make-symbolic-link are not currently supported in Tint Emacs.
