+
+ When entering the fzf interface you'll be confronted by two panes. The
+ one on the left contains every possible task you can schedule, the one
+ on the right contains the list of selected tasks. In other words, the
+ tasks that will be scheduled once you you press <enter>.
+
+ At first fzf will automatically select whichever task is under your
+ cursor, which simplifies the case when you are looking for a single
+ task. But normally you'll want to select many tasks. To accomplish
+ you'll generally start by typing a query in the search bar to filter
+ down the list of tasks (see Extended Search below). Then you'll either:
+
+ A) Move the cursor to each task you want and press <tab> to select it.
+ Notice it now shows up in the pane to the right.
+
+ OR
+
+ B) Press <ctrl-a> to select every task that matches your filter.
+
+ You can delete your query, type a new one and select further tasks as
+ many times as you like. Once you are happy with your selection, press
+ <enter> to push the selected tasks to try.
+
+ All selected task labels and their dependencies will be scheduled. This
+ means you can select a test task and its build will automatically be
+ filled in.
+
+
+ Keyboard Shortcuts
+ ------------------
+
+ When in the fuzzy finder interface, start typing to filter down the
+ task list. Then use the following keyboard shortcuts to select tasks:
+
+ Ctrl-K / Up => Move cursor up
+ Ctrl-J / Down => Move cursor down
+ Tab => Select task + move cursor down
+ Shift-Tab => Select task + move cursor up
+ Ctrl-A => Select all currently filtered tasks
+ Ctrl-D => De-select all currently filtered tasks
+ Ctrl-T => Toggle select all currently filtered tasks
+ Alt-Bspace => Clear query from input bar
+ Enter => Accept selection and exit
+ Ctrl-C / Esc => Cancel selection and exit
+ ? => Toggle preview pane
+
+ There are many more shortcuts enabled by default, you can also define
+ your own shortcuts by setting `--bind` in the $FZF_DEFAULT_OPTS
+ environment variable. See `man fzf` for more info.
+
+
+ Extended Search
+ ---------------
+
+ When typing in search terms, the following modifiers can be applied:
+
+ 'word: exact match (line must contain the literal string "word")
+ ^word: exact prefix match (line must start with literal "word")
+ word$: exact suffix match (line must end with literal "word")
+ !word: exact negation match (line must not contain literal "word")
+ 'a | 'b: OR operator (joins two exact match operators together)
+
+ For example:
+
+ ^start 'exact | !ignore fuzzy end$
