Use of shortcut keys used by Xcode

Have you just started using Xcode to find the shortcuts for the previously familiar development environment? How to run quickly, stop, edit and so on, are different. Quickly mastering these shortcuts can provide the efficiency of development.

In fact, the shortcut keys in the Xcode toolbar are marked with, but some symbols and your keyboard symbols do not match up. The shortcut keys in the following toolbar summarize the usage of common shortcut keys.

First, about running debugging

1, run, stop, all in the product of the toolbar.

Command + R runs.

Command +. Stop it

2, F6 single-step debugging, F7 jump, F8 continue, and Eclipse,vs similar

Second, navigation

This is the shortcut key in the navigation.

To explain here, some students may not know what the symbol inside, the flower key We all know, is the command key, the other several keys that, how on the keyboard can not find it? No hurry, look at the picture:

In fact, we often use the option, control, SHIFT key.

1, switch the head file and M. file, very practical

Command + control+ up and DOWN ARROW keys

2, go back, fallback, why use Ah, is to go back to the last page you opened.

Control+command+ LEFT Arrow

Go forward back to the page you opened earlier

Control+command+ RIGHT Arrow

Third, file

OS x text Editing rarely used shortcut keys (go from http://www.ib66.net.cn/bbs/view/id-39)

With computers, word processing is the most common task. In the process of word processing, skilled use of a variety of shortcut keys to improve the efficiency of the decisive significance. (Getting any software-even the operating system-to study its shortcuts is the best habit of working with computers, 1.) ）

The following is an emphasis on MB/MBP/MB Air's notebook keyboard (no f13~f15, no small numeric keypad).

1. The following shortcuts are common shortcut keys at the system level :

Command + A: Select All
Command + C: Copy
Command + V: Paste
Command + X: Cut
Command + Z: Undo
Shift + Command + Z: Undo the "undo" action you just made 2

2. In the text input area, move the cursor method :

up/down/left/right: Move cursor (one character/line) to (up/down/left/right)
Option + left/right: Moves the cursor to a word (before/after) (does not recognize "word" when processing Chinese, no difference from left/right)
Commandmand + left/right: Moves the cursor to the beginning/end of the line
Option + up/down: Moves the cursor to the beginning/end of this paragraph
Command + up/down: Moves the cursor to the beginning/end of the document

3. How to select text :

Click at the beginning and then press Shift key to click at the end;
Click twice at the beginning, then drag the pointer to the end, and click;
Press the Shift key and press the UP or down key (you can also use Option or Command )
Double clickto select the word where the cursor is located;
Triple Click: Combo Three, check the paragraph where the cursor is located (this is important)

4. Delete 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 useful:

Command + Delete: Delete the cursor to the beginning of the line
Control + K: Delete cursor to the end of this paragraph
control + Y: Paste the content you just deleted with control + K or Command + Delete to where the cursor is located

There is also a very interesting and useful shortcut key,Control + T: The position of the two subtitles before and after the cursor is swapped. However, the fit Chinese input method sets this key to "simplified traditional input switching", so the shortcut cannot be used when the Chinese input is active.

5. English spelling Tools

Shift + Command +; Bring up the spelling checker dialog box.

F5 complements the current word. In the TextEdit program, you can also use ESC to view spelling suggestions. (The cursor should be located after the English letter)

6. Rich Text Editing

Plain text files (TXT) are not formatted, but Rich Text (RTF, and so on) is available in a variety of formats, and the shortcut keys for formatting are basically generic:

Command + B: Aggravating
Command + I: Tilt
Command + U: Underline

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

Command + {: on the Left
Command +}: on the right
Command + |: Center

Control + Command + U: Convert selected text to uppercase format (Upper case)
Control + Command + L: Convert selected text to lowercase format (Lower case)
Control + Command + C: Converts the first letter of the selected text to uppercase format (capitalize)

Command + K: Insert Hyperlink

Shift + Option + Command + V: Paste in the same format as the cursor

7. In-Document search

Command + F: Search
Command + G: Search the next place
Shift + Command + G: Search Previous

8. Enter special characters

option and Shift + option This function key with other single key combinations, you can enter a variety of special characters 3:

Key table after option is pressed

Press SHIFT + OPTION after the key table

9. Fit Chinese Input Method

shift: Toggle between English and Chinese
Command + Space: Toggle Input Method
Shift + Space: full-width character switching
Control +.: Punctuation Toggle in English and Chinese
Control + T: Simplified traditional input switch

The Fit Input method is a "good enough" input method even though it has stopped continuing to develop and is maintained by tianyu263 alone. Like all modern input methods, it has the ability to "automatically learn" based on user input (that is, automatically remembers the user's choice). For example, when you select a "Custom Vocabulary" and then enter the same pinyin later, the "Custom Vocabulary" is ranked first. However, sometimes accidentally entered the error, for example, obviously want to enter "custom Vocabulary", but entered into a "custom word will", then once you enter this pinyin, "custom times" will be ranked first. In this case, you can enter the "custom vocabulary" after the pinyin does not press "space" or "enter", but by Option + 1: Delete the "wrong memory", and then re-select the correct:

Finally, for the use of "desktop keyboards", see this article I found on Harvard's website: "Cocoa Text system–default Mac OS X System Key Bindings" 4.

1. However, I wonder why most of the documents that introduce shortcut keys are not "categorized by function" but "alphabetically"-who remembers? [?]
2. As Windows turned over the user, find this key combination spent a good while ... [?]
3. I can't get it out. The MacBook presses the option key on the soft keyboard picture and has to find a picture of the desktop keyboard on the Web [?]
4. The last two are also from this article.
