It does +not enter Caret mode at all. + +The letter `v` was chosen for these shortcuts because that’s what Vim uses to +enter its Visual mode, which was an inspiration for VimFx’s Caret mode. + +### Caret mode commands + +Caret mode uses [Firefox’s own Caret mode] under the hood. This means that you +can use the arrows keys, ``, ``, `` and `` +(optionally holding ctrl) to move the caret as usual. Hold shift while moving +the caret to select text. + +In addition to the above, VimFx provides a few commands inspired by Vim. + +- `h`, `j`, `k`, `l`: Move the caret left, down, up or right, like the arrow + keys. + +- `b`, `w`: Move the caret one word backward or forward, like `` and + `` but a bit “Vim-adjusted” (see the section on Vim below) in order + to be more useful. + +- `0` (or `^`), `$`: Move the caret to the start or end of the line. + +The above commands (except the ones moving to the start or end of the line) +accept a _count._ For example, press `3w` to move three words forward. + +Press `v` to start selecting text. After doing so, VimFx’s commands for moving +the caret select the text instead of just moving the caret. Press `v` again to +collapse the selection again. (Note that after pressing `v`, only VimFx’s +commands goes into “selection mode,” while Firefox’s work as usual, requiring +shift to be held to select text.) + +`o` moves the caret to the “other end” of the selection. If the caret is at the +end of the selection, `o` will move it to the start (while keeping the selection +intact), and vice versa. This let’s you adjust the selection in both ends. + +Finally, `y` is a possibly faster alternative to the good old ``. Other +than copying the selection to the clipboard, it also exits Caret mode, saving +you yet a keystroke. (`` is unsurprisingly used to exit Caret mode +otherwise.) + +[Firefox’s own Caret mode]: http://kb.mozillazine.org/Accessibility_features_of_Firefox#Allow_text_to_be_selected_with_the_keyboard + +### Workflow tips + +If you’re lucky, the text you want to copy is located within a single element +that contains no other text, such as the text of a link or an inline code +snippet. If so, using the `yv` command (which copies an entire element without +entering Caret mode) is the fastest. + +If you want to copy _almost_ all text of an element, or a bit more than it, use +the `zv` command (which selects an entire element). Then adjust the selection +using the various Caret mode commands. Remember that `o` lets you adjust both +ends of the selection. + +In all other cases, use the `v` command to place the caret close to the text you +want to copy. Then move the caret in place using the various Caret +mode commands, hit `v` to start selecting, and move the again. + +Use `y` to finish (or `` to abort). Alternatively, use the `` key +to open the context menu for the selection. + +### For Vim users + +As seen above, Caret mode is obviously inspired by Vim’s Visual mode. However, +keep in mind that the point of Caret mode is to **copy text using the keyboard, +not mimicing Vim’s visual mode.** I’ve found that selecting text for _copying_ +is different than selecting code for _editing._ Keep that in mind. + +Working with text selection in webpages using code is a terrible mess full of +hacks. New commands will only be added if they _really_ are worth it. + +A note on VimFx’s `b` and `w`: They work like Vim’s `b` and `w` (but a “word” is +according to Firefox’s definition, not Vim’s), except when there is selected +text and the caret is at the end of the selection. Then `b` works like Vim’s +`ge` and `w` works like Vim’s `e`. The idea is to keep it simple and only +provide two commands that do what you want, rather than many just to mimic Vim. + + ## Ignore mode `` Ignore mode is all about ignoring VimFx commands and sending the keys to the diff --git a/documentation/modes.md b/documentation/modes.md index ba1d639..00fecf0 100644 --- a/documentation/modes.md +++ b/documentation/modes.md @@ -33,8 +33,11 @@ These are the modes of VimFx: make sense to [enter Ignore mode by default][blacklist] and stay in Ignore mode most of the time, occasionally popping into Normal mode. -- Hints mode.
