Text and text explanations use of common xcode shortcuts

When I first started using xcode, did I find that no shortcut keys were available for familiar development environments? How to quickly run, stop, edit, and so on are all different. Quickly Master these shortcuts to provide development efficiency.

In fact, the shortcut keys are marked in the toolbar of xcode, but some symbols do not match the symbols on your keyboard. The shortcut keys in the toolbar below summarize the usage of common shortcut keys.

 

I. About running debugging

1. Running and stopping are all in the product on the toolbar.

Command + R run.

Command +. Stop

 

2. One-Step F6 debugging, F7 jump, F8 continue, similar to eclipse,

 

Ii. Navigation

This is the shortcut key in the navigation

Here, I want to explain that some people may not know what the symbol represents. We all know that the spline is the command key, and how many other keys can't be found on the keyboard? Don't worry, see the figure:

In fact, they are commonly used options, control, shift keys.

 

1. Switching header files and M. Files is very practical.

Inaccessible shortcut keys for OS X text editing(From http://www.ib66.net.cn/bbs/view/id-39)

Word processing is the most common task for computers. In the process of word processing, skillful use of a variety of shortcut keys has a decisive significance to improve work efficiency. (Taking any software, even the operating system, to study its shortcuts is the best habit of working with a computer .)

The following describes the portable keyboards (without f13 ~ F15, No keypad ).

1. The following shortcut keys are general shortcut keys for "system-level":

Command +: Select all
Command + c: Copy
Command + V: Paste
Command + x: Cut
Command + z: Undo
Shift + command + z: Undo the "undo" Action 2.

2. move the cursor in the text input area:

Up/down/left/right: Move the cursor to (top/bottom/left/right) (one character/line)
Option + left/right: Move the cursor to a word (before/after) ("word" cannot be recognized when processing Chinese, no difference with left/right)
Commandmand + left/right: Move the cursor to the beginning/end of the line
Option + up/down: Move the cursor to the beginning/end of this segment
Command + up/down: Move the cursor to the beginning/end of the document

3. method of selecting text:

Click at the beginning, and then pressShiftClick the key at the end;
Click twice at the beginning, drag the pointer to the end, and click;
PressShiftPress the upper and lower right keys (can also be usedOptionOrCommandUse)
Double click: Double-click to select the word where the cursor is located;
Triple click: Double-click the section where the cursor is located (this is important)

4. Remove text:

Delete: Remove a character before the cursor
FN + Delete: Delete a character after the cursor
Option + Delete: Delete a word before the cursor
FN + Option + Delete: Delete a word after the cursor

The following three shortcut keys are very useful:

Command + Delete: Delete the content from the cursor to the beginning of the line
Control + k: Delete content from the cursor to the end of this section
Control + Y: Will be used just nowControl + kOrCommand + DeletePaste the deleted content to the cursor

There is also an interesting and useful shortcut key,Control + T: Change the positions of two subtitles before and after the cursor. However, the fit Chinese Input Method sets this key to "simple and Traditional Chinese Input Switch". Therefore, this shortcut key cannot be used when the Chinese input is activated.

5. Spelling tools

Shift + command +;Call up the spelling check dialog box.

F5Complete the current word. In the textedit program, you can also useESCView spelling suggestions. (The cursor should be placed after an English letter)

6. Rich text editing

Plain text files (txt) are not formatted, but rich texts (such as RTF) are in various formats, and the shortcut keys for setting the format are basically common:

Command + B: Increase
Command + I: Skew
Command + u: Underline

Command ++: Increase the font size
Command +-: Reduce the font size

Command + {: Left
Command +}: Right
Command + |: Center

Control + command + u: Convert selected text to upper case)
Control + command + L: Convert selected text to lower case (lower case)
Control + command + c: Converts the first letter of the selected text to capitalize)

Command + k: Insert hyperlink

Shift + Option + command + V: Paste in the format of the cursor

7. Search in the document

Command + F: Search
Command + G: Search next location
Shift + command + G: Search for the previous position

8. Enter special characters

OptionAndShift + OptionThis function key can be combined with other single keys and can be entered with a variety of special characters 3:

Key table after option is pressed

Key table after pressing SHIFT + Option

9. fit Chinese Input Method

Shift: Switch between Chinese and English
Command + Space: Switch Input Method
Shift + Space: Full-width character Switching
Control +.: Chinese and English Punctuation Switching
Control + T: Switch between simple and Traditional Chinese Input

Although the fit input method has stopped development and is maintained independently by tianyu263, it is still a "enough" input method. Like all modern input methods, it has the ability to "automatically learn" based on user input (that is, to automatically remember users' choices ). For example, if you select a "Custom Vocabulary" and enter the same pinyin, the "Custom Vocabulary" will be ranked first. However, sometimes you may accidentally enter an error. For example, if you want to enter a "Custom word", you can enter a "Custom word". Then, once you enter this pinyin, the "custom meeting" will be ranked first. In this case, do not press "space" or "enter", but pressOption + 1: Delete this "wrong memory" and select the correct one again:

Finally, for the use of the "desktop keyboard", see the article "cocoa text system-default Mac OS x system key bindings" 4 I found on the Harvard University website.

1. However, I wonder why most documents that introduce shortcuts are not classified by function, but are arranged alphabetically? [?]
2. As a user transferred from windows, it took a while to find this key combination ...... [?]
3. I couldn't cut out the option-based keyboard picture of my MacBook, so I had to find a desktop keyboard picture online. [?]
4. The last two are also from this article.
