Usage
|
|
-----
|
|
RTV currently supports browsing both subreddits and individual submissions.
|
|
In each mode the controls are slightly different. In subreddit mode you can
|
|
browse through the top submissions on either the front page or a specific
|
|
subreddit. In submission mode you can view the self text for a submission and
|
|
browse comments.
|
|
|
|
Global Commands
|
|
Arrow Keys or `hjkl`: RTV supports both the arrow keys and vim bindings for
|
|
navigation. Move up and down to scroll through items
|
|
on the page.
|
|
`r` or `F5` : Refresh the current page.
|
|
`q` : Quit the program.
|
|
|
|
Subreddit Mode
|
|
Right or `Enter` : Open the currently selected submission in a new page.
|
|
`/` : Open a prompt to switch to a different subreddit. For
|
|
example, pressing `/` and typing "python" will open
|
|
"/r/python". You can return to Reddit's front page
|
|
by using the alias "/r/front".
|
|
|
|
Submission Mode
|
|
Right or `Enter` : Toggle the currently selected comment between hidden
|
|
and visible. Alternatively, load addition comments
|
|
identified by "[+] more comments".
|
|
Left : Exit the submission page and return to the subreddit.
