+### Toggling with a single key binding
+
+The above example uses two different key bindings to toggle between two modes,
+but can we just use a single key binding?
+
+To make a key binding behave differently each time it is pressed, we need:
+
+1. a way to store the current state. i.e. "which mode are we in?"
+2. and a way to dynamically perform different actions depending on the state.
+
+The following example shows how to 1. store the current mode in the prompt
+string, 2. and use this information (`$FZF_PROMPT`) to determine which
+actions to perform using the `transform` action.
+
+```sh
+fd --type file |
+  fzf --prompt 'Files> ' \
+      --header 'CTRL-T: Switch between Files/Directories' \
+      --bind 'ctrl-t:transform:[[ ! $FZF_PROMPT =~ Files ]] &&
+              echo "change-prompt(Files> )+reload(fd --type file)" ||
+              echo "change-prompt(Directories> )+reload(fd --type directory)"' \
+      --preview '[[ $FZF_PROMPT =~ Files ]] && bat --color=always {} || tree -C {}'

+### Switching between Ripgrep mode and fzf mode using a single key binding
+
+In contrast to the previous version, we use just one hotkey to toggle between
+ripgrep and fzf mode. This is achieved by using the `$FZF_PROMPT` as a state
+within the `transform` action, a feature introduced in [fzf 0.45.0][0.45.0]. A
+more detailed explanation of this feature can be found in a previous section -

+When using the `transform` action, the placeholder (`\{q}`) should be escaped to
+prevent immediate evaluation.

+- CTRL-T and ALT-C bindings can be disabled by setting `FZF_CTRL_T_COMMAND` and `FZF_ALT_C_COMMAND` to empty strings respectively when sourcing the script

+        export FZF_DEFAULT_COMMAND='seq 100'
+        fzf --walker=dir
+        ```
+- Shell integration scripts have been updated to use the built-in walker with these new options and they are now much faster out of the box.
+
+0.47.0
+------
+- Replaced ["the default find command"][find] with a built-in directory walker to simplify the code and to achieve better performance and consistent behavior across platforms.
+  This doesn't affect you if you have `$FZF_DEFAULT_COMMAND` set.
+    - Breaking changes:
+        - Unlike [the previous "find" command][find], the new traversal code will list hidden files, but hidden directories will still be ignored
+        - No filtering of `devtmpfs` or `proc` types
+        - Traversal is parallelized, so the order of the entries will be different each time
+    - You may wonder why fzf implements directory walker anyway when it's a filter program following the [Unix philosophy][unix].
+      But fzf has had [the walker code for years][walker] to tackle the performance problem on Windows. And I decided to use the same approach on different platforms as well for the benefits listed above.
+    - Built-in walker is using the excellent [charlievieth/fastwalk][fastwalk] library, which easily outperforms its competitors and supports safely following symlinks.
+- Added `$FZF_DEFAULT_OPTS_FILE` to allow managing default options in a file
+    - See [#3618](https://github.com/junegunn/fzf/pull/3618)
+    - Option precedence from lower to higher
+        1. Options read from `$FZF_DEFAULT_OPTS_FILE`
+        1. Options from `$FZF_DEFAULT_OPTS`
+        1. Options from command-line arguments

+- Bug fixes and improvements
+- Fixed Windows binaries
+- Downgraded Go version to 1.20 to support older versions of Windows
+    - https://tip.golang.org/doc/go1.21#windows
+- Updated [rivo/uniseg](https://github.com/rivo/uniseg) dependency to v0.4.6
+
+0.46.0
+------
+- Added two new events
+    - `result` - triggered when the filtering for the current query is complete and the result list is ready
+    - `resize` - triggered when the terminal size is changed
+- fzf now exports the following environment variables to the child processes
+  | Variable           | Description                                                 |
+  | ---                | ---                                                         |
+  | `FZF_LINES`        | Number of lines fzf takes up excluding padding and margin   |
+  | `FZF_COLUMNS`      | Number of columns fzf takes up excluding padding and margin |
+  | `FZF_TOTAL_COUNT`  | Total number of items                                       |
+  | `FZF_MATCH_COUNT`  | Number of matched items                                     |
+  | `FZF_SELECT_COUNT` | Number of selected items                                    |
+  | `FZF_QUERY`        | Current query string                                        |
+  | `FZF_PROMPT`       | Prompt string                                               |
+  | `FZF_ACTION`       | The name of the last action performed                       |
+  - This allows you to write sophisticated transformations like so
+    ```sh
+    # Script to dynamically resize the preview window
+    transformer='
+      # 1 line for info, another for prompt, and 2 more lines for preview window border
+      lines=$(( FZF_LINES - FZF_MATCH_COUNT - 4 ))
+      if [[ $FZF_MATCH_COUNT -eq 0 ]]; then
+        echo "change-preview-window:hidden"
+      elif [[ $lines -gt 3 ]]; then
+        echo "change-preview-window:$lines"
+      elif [[ $FZF_PREVIEW_LINES -ne 3 ]]; then
+        echo "change-preview-window:3"
+      fi
+    '
+    seq 10000 | fzf --preview 'seq {} 10000' --preview-window up \
+                    --bind "result:transform:$transformer" \
+                    --bind "resize:transform:$transformer"
+    ```
+  - And we're phasing out `{fzf:prompt}` and `{fzf:action}`
+- Changed [mattn/go-runewidth](https://github.com/mattn/go-runewidth) dependency to [rivo/uniseg](https://github.com/rivo/uniseg) for accurate results
+    - Set `--ambidouble` if your terminal displays ambiguous width characters (e.g. box-drawing characters for borders) as 2 columns
+    - `RUNEWIDTH_EASTASIAN=1` is still respected for backward compatibility, but it's recommended that you use this new option instead
+- Bug fixes
+
+0.45.0
+------
+- Added `transform` action to conditionally perform a series of actions
+  ```sh
+  # Disallow selecting an empty line
+  echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
+    fzf --height '~100%' --reverse --header 'Select one' \
+        --bind 'enter:transform:[[ -n {} ]] && echo accept || echo "change-header:Invalid selection"'
+
+  # Move cursor past the empty line
+  echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
+    fzf --height '~100%' --reverse --header 'Select one' \
+        --bind 'enter:transform:[[ -n {} ]] && echo accept || echo "change-header:Invalid selection"' \
+        --bind 'focus:transform:[[ -n {} ]] && exit; [[ {fzf:action} =~ up$ ]] && echo up || echo down'
+
+  # A single key binding to toggle between modes
+  fd --type file |
+    fzf --prompt 'Files> ' \
+        --header 'CTRL-T: Switch between Files/Directories' \
+        --bind 'ctrl-t:transform:[[ ! {fzf:prompt} =~ Files ]] &&
+                  echo "change-prompt(Files> )+reload(fd --type file)" ||
+                  echo "change-prompt(Directories> )+reload(fd --type directory)"'
+  ```
+- Added placeholder expressions
+    - `{fzf:action}` - The name of the last action performed
+    - `{fzf:prompt}` - Prompt string (including ANSI color codes)
+    - `{fzf:query}` - Synonym for `{q}`
+- Added support for negative height
+  ```sh
+  # Terminal height minus 1, so you can still see the command line
+  fzf --height=-1
+  ```
+  - This handles a terminal resize better than `--height=$(($(tput lines) - 1))`
+- Added `accept-or-print-query` action that acts like `accept` but prints the
+  current query when there's no match for the query
+  ```sh
+  # You can make CTRL-R paste the current query when there's no match
+  export FZF_CTRL_R_OPTS='--bind enter:accept-or-print-query'
+  ```
+  - Note that there are alternative ways to implement the same strategy
+    ```sh
+    # 'become' is apparently more versatile but it's not available on Windows.
+    export FZF_CTRL_R_OPTS='--bind "enter:become:if [ -z {} ]; then echo {q}; else echo {}; fi"'
+
+    # Using the new 'transform' action
+    export FZF_CTRL_R_OPTS='--bind "enter:transform:[ -z {} ] && echo print-query || echo accept"'
+    ```
+- Added `show-header` and `hide-header` actions
+- Bug fixes
