    For instance, if the cursor is online 30, and contours 31–35 are hidden in a fold at the subsequent monitor line, in order that the subsequent line at the monitor screens line 36, 3zf creates a brand new fold containing 3 traces as they seem at the reveal: the textual content line 30, the 5 traces inside the fold retaining traces 31–35, and the textual content line 36 displayed within the subsequent line at the monitor. complicated? a bit. chances are you'll say that the zf command counts traces based on the rule of thumb, “What you spot is what you fold. ” Let’s test another beneficial properties. First, open all of the folds with the command zO (that’s z via the letter O, no longer z by means of a zero). Now we begin seeing a few visible cues within the left margin concerning the folds we made, as proven in determine 14-6. all of the columns during this margin is named a foldcolumn. determine 14-6. All folds opened during this determine, the 1st line of every fold is marked with a minus signal (–), and the entire different traces of the fold are marked through a vertical bar or pipe personality (|). the biggest (outermost) fold is within the leftmost column, and the innermost fold is within the rightmost column. As you spot in our photograph, strains 5–25 characterize the bottom fold point (in this situation, 1), strains 15–22 characterize the following fold point (2), and features 18–20 symbolize the top fold point. Tip via default, this useful visible metaphor is grew to become off (we don’t be aware of why; maybe since it makes use of up monitor space). flip it on and outline its width with the next command: :set foldcolumns=n the place n is the variety of columns to exploit (maximum is 12, default is 0). within the determine, we use foldcolumn=5. (For these paying shut cognizance, sure, the sooner figures had foldcolumn set to three. We replaced the worth for a greater visible presentation. ) Now create extra folds to watch their results. First, refold the inner most fold, which covers strains 18–20, by way of positioning the cursor on any line in the diversity of that fold and typing zc (close fold). determine 14-7 indicates the end result. determine 14-7. After refolding traces 18–20 See the switch within the grey margin? Vim continues the visible cues, making visualization and administration of your folds effortless. Now let’s see what a regular “one line” command does to a fold. place the cursor at the folded line (18). style ~~ (toggle case for all characters within the present line). keep in mind that in Vim, ~ is an item operator (unless the suitable alternative is determined) and for this reason should still toggle the case of all of the characters within the line for this instance. subsequent, open the fold via typing zo (open fold). The code now feels like determine 14-8. determine 14-8. Case swap utilized to a fold this can be a strong characteristic. Line instructions or operators act at the complete textual content represented by way of a fold line! Admittedly this can appear like a contrived instance, however it illustrates properly the opportunity of this system. word Any motion on a fold impacts the total fold. for example, in determine 14-7, if you happen to place the cursor over line 18—a fold hiding strains 18 via 20—and kind dd (delete line), all 3 strains are deleted and the fold is got rid of.
