```
Here is the complete list of configuration options:
```
### ROOT: Directory containing the collections
### COLLECTION_LABELS: Mappings between collections and labels
### SYNC_CMD (optional): Synchronization command
### DAY_START (optional): Hour of start of the day (defaults to 8)
### DAY_END (optional): Hour of end of the day (defaults to 18)
### EDITOR (optional): Your favorite editor, is usually already exported
### TZ (optional): Your favorite timezone, usually system's choice
### LC_TIME (optional): Your favorite locale for date and time
### ZI_DIR (optional): Location of tzdata, defaults to /usr/share/zoneinfo
```
Usage
-----
Use the default `fzf` keys to navigate your calendar entries, e.g., `ctrl-j`
and `ctrl-k` for going down/up in the list.
After starting `fzf-vcal`, you are presented with a view on the current week.
You can navigate that week using `j` and `h` for going down and up.
Hit `<enter>` on any day, and you will see all entries for that date, including
previews. In both, the week and day views, you can add entries by hitting
`ctrl-n`.
Here is the list of all available keybindings:
### Week view
| Key | Action |
| --- | ------ |
| `q` | quit |

| `ctrl-l` | go to next month |
| `ctrl-h` | go to previous month |
| `alt-l` | go to next year |
| `alt-h` | go to previous year |
| `ctrl-r` | reload and go to week that contains `today` |
| `ctrl-g` | interactively go to specified week |
| `ctrl-t` | set timezon |
| `ctrl-s` | synchronize |
| `ctrl-n` | add new entry |
| `\` | search all appointment s |
| `x` | Cancel and confirm entry |
| `c` | Unconfirm and confirm entry |
### Day view
| Key | Action |
| --- | ------ |
| `enter` | edit appointment |
| `a` | open attachment list of appointment |
| `j` | down |
| `k` | up |
| `l` | go to next day |
| `h` | go to previous day |
| `ctrl-l` | go to next week |
| `ctrl-h` | go to previous week |
| `alt-l` | go to next month |
| `alt-h` | go to previous month |
| `ctrl-r` | reload and go to `today` |
| `ctrl-g` | interactively go to specified day |
| `ctrl-t` | set timezon |
| `ctrl-s` | synchronize |
| `ctrl-n` | add new entry |
| `ctrl-alt-d` | delete entry |
| `w` | toggle line wrap in preview |
| `ctrl-d` | down in preview |
| `ctrl-u` | up in preview |
| `alt-v` | view raw iCalendar file |
| `esc` | return to week view, you can also do this with `q` or `backspace` |
### There is more
Here is the list of available keybindings:
| Key | View | Action |
| --- | ---- | ------ |
| `enter` | week view | Switch to day view |
| `ctrl-n` | week view | Make a new entry |
| any letter | week view | Search in the list of all entries |
| `backspace` on empty query | week view | Undo search |

| `ctrl-alt-d` | week view | Go forth one month |
| `ctrl-s` | week view | Run the synchronization command |
| `ctrl-l` | week view | Go to current week |
| `ctrl-g` | week view | Goto date |
| `enter` | day view | Open selected calendar entry in your favorite `$EDITOR` |

preferred timezone. The latter is in particular helpful if you want to take a
look at your calendar relative to being in another timezone.
