+## Demos
+
+### Copy and Move
+
+Copy (default `c`) and move (default `m`) mark (default `space` and invert
+`C-space`) files.
+
+![demo_copy](.github/demo_copy.gif)
+
+First input a copy source file name (or path).  The default source is a file
+name on the cursor.  If files are marked, this step is skipped.
+
+Second input a copy destination path and start copy processing.  The default
+destination is a neighboring directory path.
+
+During processing draws copying file count, size and name, progress percent,
+gauge, bps and estimated time of arrival.
+
+If the source file type is a directory, recursively copy.  Also copy
+modification time and permissions.
+
+Rise a override confirm dialog `[y/n/Y/N]` if the name same as source file
+exists in the destination.  This dialog means:
+
+* `y` is overwrite only this file
+* `n` is not overwrite only this file
+* `Y` is overwrite all later file
+* `N` is not overwrite all later file
+
+Copy process works asynchronously.  And processed in the order if you run
+multiple copies.
+
+Note that copy process can not interrupt.  If you want to interrupt, please quit
+the application (default `q` `Q`).
+
+### Bulk Rename
+
+Bulk renaming (default `R`) for mark (default `space` and invert `C-space`)
+files.
+
+Rename by the regexp pattern.  Input like the vim substituting style
+(regexp/replaced).  Display and confirm matched files and replaced names before
+rename.
+

+
+### Finder (Filtering search)
+
+The finder (default `f` `/`) filters files in the directory.
+
+Input characters recognizes as the regexp.  Case insensitive when inputs
+lowercase only, on the other hand case sensitive when contains uppercase.
+
+Delete characters by `C-h` and `backspace` (default).  Can select input
+histories by `M-p` and `M-n` (default).
+
+Other than character inputs (exclude a space) and the finder keymap pass to the
+main input.
+
+Hit reset key (default `C-g` `C-[` means `Esc`) to clear filtering.

+
+### Glob
+
+Glob is matched by wild card pattern in the current directory (default `g` and
+recursive `G`).
+
+Hit reset key (default `C-g` `C-[` means `Esc`) to clear glob patterns.
+
+![demo_glob](.github/demo_glob.gif)
+
+### Layout
+
+Directory windows position are allocated by layouts of tile, tile-top,
+tile-bottom, one-row, one-column and fullscreen.
+
+View menu (default `v`), run layout menu and select layout:
+
+![demo_layout](.github/demo_layout.gif)
+
+### Execute Terminal and Shell
+
+Shell mode (default `:` and suspended `;`) runs a terminal and execute shell
+such as bash and tmux.  The cmdline completion (file names and commands in
+$PATH) is available (default `C-i` that means `tab`).
+
+For example, spawns commands by bash in a gnome-terminal new tab:
+
+![demo_shell](.github/demo_shell.gif)
+
+The terminal immediately doesn't close when command finished because check
+outputs.
+
+If goful is running in tmux, it creates a new window and executes the command.
+
+### Expand Macro
+
+macro        | expanded string
+-------------|------------------
+`%f` `%F`   | File name/path on cursor
+`%x` `%X`   | File name/path with extension excluded on cursor
+`%m` `%M`   | Marked file names/paths joined by spaces
+`%d` `%D`   | Directory name/path on cursor
+`%d2` `%D2` | Neighbor directory name/path
+`%~f` ...   | Expand by non quote
+`%&`        | Flag to run command in background
+
+The macro is useful if do not want to specify a file name when run the shell.
+
+Macros starts with `%` are expanded surrounded by quote, and those starts with
+`%~` are expanded by non quote.  The `%~` mainly uses to for cmd.exe.
+
+Use `%&` when background execute the shell such as GUI apps launching.
