Welcome to the Helix editor! Helix is different from editors
|
|
|
|
you might be used to in that it is modal, meaning that it has
|
|
|
|
different modes for editing text. The primary modes you will
|
|
|
|
use are Normal mode and Insert mode. While in Normal mode, the
|
2022-04-29 04:52:11 +03:00
|
|
|
keys you type won't actually type text. Instead, they will
|
2021-08-13 04:13:17 +03:00
|
|
|
perform various actions with the text. This allows for more
|
|
|
|
efficient editing. This tutor will teach you how you can make
|
|
|
|
use of Helix's modal editing features. To begin, ensure your
|
|
|
|
caps-lock key is not pressed and hold the j key until you reach
|
|
|
|
the first lesson.

The cursor can be moved using the h, j, k, l keys, as shown

above. The cursor/arrow keys will also work, but it is faster
|
|
|
|
to use the hjkl keys as they are closer to the other keys you

will be using. Try moving around to get a feel for hjkl.

position of the cursor. There are a few other ways you can

Common examples of insertion commands include:
|
|
|
|
i - Insert before the selection.
|
|
|
|
a - Insert after the selection. (a means 'append')
|
|
|
|
I - Insert at the start of the line.

A - Insert at the end of the line.

As you saw, typing w moves the cursor forward until the start
|
2021-08-13 04:13:17 +03:00
|
|
|
of the next word, selecting the text traversed. This is useful
|
|
|
|
for moving around text and for selecting text to operate on.
|
|
|
|
|
|
|
|
Some common motions include:
|
|
|
|
w - Move forward to before the beginning of the next word.
|
|
|
|
e - Move forward to the end of the current word.
|
|
|
|
b - Move backward to the beginning of the current word.
|
|
|
|
|
|
|
|
The w,e,b motions also have counterparts - W,E,B - which
|
|
|
|
traverse WORDS instead of words. WORDS are only separated by
|
|
|
|
whitespace, whereas words can be separated by other characters
|
|
|
|
in addition to whitespace.
|
|
|
|
|
|
|
|
All of these motions select the text they traverse.

n and N both refer to register /, this means we can set that

register without having to type in a search.

Type * to copy the primary selection into register /, setting
