Because ios10 was just released, new emulators and adaptations needed to be added in the project, so xcode8 was upgraded on September 20th. However, after the upgrade, it was found that the shortcut key commed+/ was invalid, and it still failed after repeated restarts for N times. Later, it was found that Xcode8 blocked the use of plug-ins. In terminal input sudo/usr/libexec/xpccachectl can, introduce some commonly used xcode shortcuts below (from http://www.cnblogs.com/langtianya/p/3888157.html)

OS X’s text editors rarely use shortcuts (from http://www.ib66.net.cn/bbs/view/id-39)
Word processing is the most common task on a computer. In the process of word processing, skilled use of a variety of shortcut keys to improve work efficiency has a decisive significance. Taking any piece of software — even an operating system — and studying its shortcut keys is a good habit for working with a computer
).
The following focuses on MB/MBP/MB Air notebook keyboard (no F13~F15, no small number keyboard).
- The following shortcuts are common system level shortcuts:
Command + A: Select all Command + C: copy Command + V: paste Command + X: cut Command + Z: undo Shift + Command + Z: Undo
- In the text input area, move the cursor:
Up/Down/Left/Right: Moves the cursor (one character/line) to (Up/Down/Left/Right) Option + Left/Right: Commandmand + Left/Right: Move the cursor to the beginning/end of a line Option + Up/Down: Command + Up/Down: Moves the cursor to the beginning/end of a document
- Method of selecting text
:
Click at the beginning and hold Shift
The key clicks at the end; Click twice at the beginning, then drag the pointer to the end and click once;
Shift followed by up, down, left, and right (can also be used with Option or Command)
Double Click: select the word where the cursor is;
Select the paragraph where the cursor is (this is important).
- Delete the word
:
Delete
: Deletes a character before the cursor
Fn + Delete: deletes a character after the cursor
Option + Delete: Deletes a word before the cursor
Fn + Option + Delete: Deletes a word after the cursor
The following three shortcuts are very useful:
Command + Delete
: Deletes the content that moves the cursor to the beginning of the line
Control + K: Delete the cursor to the end of the paragraph
Control + Y: Paste the content you just deleted with Control + K or Command + Delete to the point where the cursor is
There’s also an interesting and useful shortcut, Control + T
: Switch the position of the two subtitles before and after the cursor. However, the FIT Chinese input method sets this key to “switching between Traditional and simplified Chinese input”, so this shortcut cannot be used when Chinese input is active.
- English spelling tool
Shift + Command + ;
Bring up the spell check dialog box.
F5
Complete the current word. In the TextEdit program, you can also use ESC to view spelling suggestions. (The cursor position should be after the English letter)
- Rich text editor
Plain text files (TXT) have no format, but rich text (RTF, etc.) comes in a variety of formats, and the formatting shortcuts are almost universal:
Command + B
: add
Command + I: tilt
Command + U: underscore
Command + +
: Increases the font size
Command + – : reduces the font size
Command + {
: on the left
Command +} : Lean to the right
The Command + | : center
Control + Command + U
: Converts selected text to uppercase format (Upper case)
Control + Command + L: Convert selected text to Lower case
Control + Command + C: Capitalize the first letter of the selected text
Command + K
: Insert hyperlinks
Shift + Option + Command + V
: Paste in the format of the cursor
- In-document search
Command + F
Search:
Command + G: Searches for the next location
Shift + Command + G: Search for the previous location
- Enter special characters
Option
The Shift + Option function key can be combined with other single keys to enter various special characters 3:
Press the key table after Option
Press the key table after Shift + Option
- FIT Chinese input method
Shift
: Switching between English and Chinese
Command + Space: Changes the input method
Shift + Space: Full character switch
Control +. : Chinese and English punctuation switch
Control + T: Switching between traditional and simple input
The FIT input method although currently discontinued continues to be developed by Tianyu263
Self-maintenance, but it’s still a “good enough” input method. Like all modern input methods, it has the ability to continuously “auto-learn” (that is, automatically remember the user’s choices) based on the user’s input. For example, if you select the “custom word” once and type the same pinyin in the future, the “custom word” will be ranked first. However, sometimes careless input errors, for example, clearly want to enter “custom words”, but entered into “custom words”; So once you enter this pinyin in the future, “custom will” will be ranked first. In this case, instead of pressing “space” or “enter” after entering the pinyin of “custom vocabulary”, press Option + 1 to delete the “wrong memory” and then select the correct one again:
