Intellij运行快捷方式（Mac）

Question

运行为^ R（CTRL R），但在Mac上不起作用。

反正我可以重新编写使用OPTION R之类的快捷方式吗？

Answer 1

默认情况下，在Windows / Linux中public class Presidents { public int presidentNumber; public String presidentName; public int startingYear; public int endingYear; Presidents [] president; public Presidents(int PresidentNumber, String NameOfPresident, int StartingYear, int EndingYear) { this.presidentNumber = PresidentNumber; this.presidentName = NameOfPresident; this.startingYear = StartingYear; this.endingYear = EndingYear; } public Presidents() { } public Presidents [] PresidentList () { president= new Presidents [45]; president [0] = new Presidents(1, "George Washington", 1789, 1797); president [1] = new Presidents(2, "John Adams", 1797, 1801); president [2] = new Presidents(3, "Thomas Jefferson", 1801, 1809); president [3] = new Presidents(4, "James Madison", 1809, 1817); president [4] = new Presidents(5, "James Monroe", 1817, 1825); president [5] = new Presidents(6, "John Quincy Adams", 1825, 1829); president [6] = new Presidents(7, "Andrew Jackson", 1829, 1837); president [7] = new Presidents(8, "Martin Van Buren", 1837, 1841); president [8] = new Presidents(9, "William Henry Harrison", 1841, 1841); president [9] = new Presidents(10, "John Tyler", 1841, 1845); president [10] = new Presidents(11, "James K. Polk", 1845, 1849); president [11] = new Presidents(12, "Zachary Taylor", 1849, 1850); president [12] = new Presidents(13, "Millard Fillmore", 1850, 1853); president [13] = new Presidents(14, "Franklin Pierce", 1853, 1857); president [14] = new Presidents(15, "James Buchanan", 1857, 1861); president [15] = new Presidents(16, "Abraham Lincoln", 1861, 1865); president [16] = new Presidents(17, "Andrew Johnson", 1865, 1869); president [17] = new Presidents(18, "Ulysses S.

Enter a number between 1 and 45"); Scanner kb = new Scanner (System.in); int input = kb.nextInt(); while (input < 1 || input > 45) { System.out.println("Enter a number between 1 and 45"); input = kb.nextInt(); } Presidents president = new Presidents (); Presidents [] presidentList = president.PresidentList(); //System.out.println(presidentList [0].presidentName); for(int i=0;i<input;i++) { Presidents p = presidentList[i]; System.out.println(p.presidentNumber+", "+p.presidentName+", "+p.startingYear+", "+p.endingYear); } kb.close(); } } （Run），而在Mac中是Ctrl + R。

也许您还有另一个键盘映射，请在Shift + F10-> ^R-> File-> Settings-> Keymap-> {{1 }}。

Answer 2

为什么不使用intellij-idea中的“键盘映射”选项来找出您真正需要的快捷键？

Answer 3

您可以在以下位置更改绑定 首选项->键盘映射->主菜单->运行->运行

至于为什么^ R不起作用，您是否有机会使用IdeaVim插件？它会为重做获取^ R（通常是vim ^ R绑定），并且-不幸的是-IntelliJ键盘图中没有显示该指示。
